Korean Traditional Elements and Contemporary Compositional Techniques in Hyowon Woo’s Choral Music As Reflected in Gloria (open access)

Korean Traditional Elements and Contemporary Compositional Techniques in Hyowon Woo’s Choral Music As Reflected in Gloria

Among native Korean choral composers, Hyowon Woo has emerged as one of the most significant representatives of choral genre, both in Korea and internationally. She has created a new style of choral music that combines traditional Korean musical elements with contemporary Western compositional techniques, in a synthesis that generates new sonorities and effects. Her choral music falls into three basic categories: music employing direct quotation of Korean folk tunes or other elements, which produce typical Korean sonorities; music using Western practices, which produce modern and Western flavors; and music combining Korean traditional methods with modern Western concepts. Hyowon Woo’s unique contribution to contemporary Korean choral music is ideally represented by her Gloria, which will form the basis for this study. Because traditional Korean music culture has such a strong presence and influence on her choral compositions, detailed knowledge of these elements are essential for the study and performance of her work. The combination of traditional Korean music and Western contemporary techniques lies at the core of her compositional style, and is the principal focus of this study. A detailed understanding of these stylistic elements, both Korean and Western, and how they work together to achieve the composer’s purpose and vision, …

Child Teacher Relationship Training As a Head Start Early Mental Health Intervention for Children Exhibiting Disruptive Behavior:  an Exploratory Study (open access)

Child Teacher Relationship Training As a Head Start Early Mental Health Intervention for Children Exhibiting Disruptive Behavior: an Exploratory Study

This exploratory study examined the effectiveness of child teacher relationship training (CTRT) with at-risk preschool children exhibiting disruptive behavior. The participants included a total of 23 Head Start teachers and their aides, and children identified by their teachers as exhibiting clinical or borderline levels of externalizing behavior problems. Teacher participants included 22 females and 1 male; demographics were reported as 56% Hispanic ethnicity, 17% Black American, and 22% European American. Child participants included 15 males and 5 females; demographics were reported as 60% Hispanic, 30% Black American, and 10% European American. A 2 by 3 (Group x Repeated Measures) split plot ANOVA was used to analyze the data. According to teacher reports using the Teacher Report Form (C-TRF) and blinded raters’ reports using the Direct Observation Form (DOF) to assess disruptive behaviors, children whose teachers received the CTRT intervention demonstrated statistically significant decreases (p < .05) in externalizing behaviors on the C-TRF and total problems on the DOF from pre- to mid- to post-test, compared to children whose teachers participated in the active control group. The CTRT intervention demonstrated large treatment effects on both measures (C-TRF: ?p2 =.173; DOF: ?p2=.164) when compared to CD, revealing the practical significance of the …

The Effects of Increasing Rates of Reinforcement Through an Alternative Fluent Behavior on the Acquisition and Extinction of Behavior in Dogs (open access)

The Effects of Increasing Rates of Reinforcement Through an Alternative Fluent Behavior on the Acquisition and Extinction of Behavior in Dogs

The purpose of the present study was to experimentally investigate the effects of interspersing the opportunity to perform a fluent behavior during the acquisition of a new behavior. The experimenter trained left and right paw movements in domestic canines using a multiple treatment design. One paw movement was trained with a typical shaping procedure while the other was trained with an opportunity to perform a fluent behavior, touching the dog’s nose to a plastic disc, following each successive approximation in the shaping procedure. Two extinction phases were implemented during the experiment. The results showed that higher rates of reinforcement were achieved primarily following changes in criteria for reinforcement for the behavior in acquisition. There were no effects on rate of acquisition of the behavior, but adding an alternative fluent behavior may have slowed the differentiation between the reinforced behavior and alternative behaviors for one dog. The behavior trained with the addition of an alternative fluent behavior extinguished more quickly than in the control condition and extinguished at similar rates to the opposite leg movement. This suggests that the technique of offering an alternative fluent behavior may facilitate the chaining of the opposite behavior with the behavior targeted for reinforcement.

Cardinal Giovanni Battista De Luca: Nepotism in the Seventeenth-century Catholic Church and De Luca's Efforts to Prohibit the Practice (open access)

Cardinal Giovanni Battista De Luca: Nepotism in the Seventeenth-century Catholic Church and De Luca's Efforts to Prohibit the Practice

This dissertation examines the role of Cardinal Giovanni Battista de Luca in the reform of nepotism in the seventeenth-century Catholic Church. Popes gave very large amounts of money to their relatives and the burden of nepotism on the Catholic Church was very onerous. The Catholic Church was crippled by nepotism and unable to carry out its traditional functions. Although Cardinal de Luca and Pope Innocent XI worked tirelessly to end nepotism, they were thwarted in their attempts by apprehension among the Cardinals concerning conciliarism and concerning the use of reform measures from the Council of Trent; by Gallicanism and the attempts of the French King to exercise power over the French Church; and by the entrenchment of nepotism and its long acceptance within the Church. Cardinal de Luca and Innocent XI were not able to push through reforms during their lifetimes but Pope Innocent XII was able to complete this reform and pass a reform Bull. This dissertation has two complementary themes. First, a confluence of circumstances allowed for the unfettered growth of nepotism in the seventeenth-century Church to the point of threatening the well-being of the Catholic Church. Reform was not undertaken until the threat to Church finances was …

Untangling the Effects of Scheduled Exercise on Child Engagement, Stereotypy, and Challenging Behavior (open access)

Untangling the Effects of Scheduled Exercise on Child Engagement, Stereotypy, and Challenging Behavior

There is limited research pertaining to the effects of exercise on the behavior of children with autism. Previous researchers focused on exploring the dimensions of the exercise itself, leaving a functional account of the effects of exercise undetermined. There is recent evidence that exercise suppresses responses maintained by automatic reinforcement. The purpose of the present study was to better identify the relevant independent variable in such research and to assess if there were differential effects of exercise across functional response classes. The experimenter conducted a trial-based functional analysis and then implemented a sedentary or vigorous activity on alternating days to determine the impact of exercise on engagement, stereotypy, and challenging behavior. Results across functional response classes were variable as were data across individual sessions. There was a mean suppression of behavior maintained by nonsocial reinforcement during post-sedentary (4.3%) and post-exercise sessions (2.3%). A discussion of the role of matched stimulation and heart rate as a pertinent variable follows.

Motivation and Resilience in Art Education: Insight and Inspiration From the Lives and Careers of Two Taiwanese College Art Teachers (open access)

Motivation and Resilience in Art Education: Insight and Inspiration From the Lives and Careers of Two Taiwanese College Art Teachers

This narrative study explores how two Taiwanese college art teachers’ lives and teaching experiences illustrate the ways they cultivate resilience and motivation to sustain professional commitments amidst challenges in their teaching careers. I use the life story interview as my methodology and a three-dimensional space approach to code and analyze my data to retell their stories about how resilience and motivation have guided them as they negotiated dilemmas in teaching. The participants’ stories demonstrate that in order to be motivated, teachers must satisfy their basic needs, which, in the language of Maslow’s need theory, include secure income, safety, love and belonging, respect, and personal accomplishment. To be resilient, art teachers need to facilitate self-efficacy as an essential belief to face challenges, and they also must gain support from family members, students, school administrators, and fellow members of professional organizations as external support resources. This study also illuminates the significance of international educational exchanges, the teaching knowledge constructed through layers of life and professional experience, and the importance of creating dialogue to address teachers’ challenges. Recommendations for future study include exploring further the relationship between motivation and resilience, specifying how gender difference affects the ways participants tell their stories, investigating how …

First Principles Calculations of the Site Substitution Behavior in Gamma Prime Phase in Nickel Based Superalloys (open access)

First Principles Calculations of the Site Substitution Behavior in Gamma Prime Phase in Nickel Based Superalloys

Nickel based superalloys have superior high temperature mechanical strength, corrosion and creep resistance in harsh environments and found applications in the hot sections as turbine blades and turbine discs in jet engines and gas generator turbines in the aerospace and energy industries. The efficiency of these turbine engines depends on the turbine inlet temperature, which is determined by the high temperature strength and behavior of these superalloys. The microstructure of nickel based superalloys usually contains coherently precipitated gamma prime (?) Ni3Al phase within the random solid solution of the gamma () matrix, with the ? phase being the strengthening phase of the superalloys. How the alloying elements partition into the and ? phases and especially in the site occupancy behaviors in the strengthening ? phases play a critical role in their high temperature mechanical behaviors. The goal of this dissertation is to study the site substitution behavior of the major alloying elements including Cr, Co and Ti through first principles based calculations. Site substitution energies have been calculated using the anti-site formation, the standard defect formation formalism, and the vacancy formation based formalism. Elements such as Cr and Ti were found to show strong preference for Al sublattice, whereas Co …

Correcting the Record: a Comparison of Vladimir Ashkenazy’s Urtext-based Edition of Pictures at an Exhibition with Orchestration By Ravel and Stokowski (open access)

Correcting the Record: a Comparison of Vladimir Ashkenazy’s Urtext-based Edition of Pictures at an Exhibition with Orchestration By Ravel and Stokowski

Modest Mussorgsky (1839-1881) never published his piano suite, Pictures at an Exhibition. The first publication of the Pictures was Nikolai Rimsky-Korsakov’s (1844-1908) piano edition in 1886, five years after Mussorgsky’s death. Among several piano editions of Pictures, Manfred Schandert’s urtext piano edition of 1984 has shed new light on the piano suite. The urtext edition is based on a facsimile of Mussorgsky’s autograph, and Schandert’s authoritative urtext contains all of Mussorgsky’s musical indications that previous editions neglected to include. Previous orchestrations based on less comprehensive editions include well-known orchestrations by Maurice Ravel (1875-1937) and Leopold Stokowski (1882-1977). Vladimir Ashkenazy (b. 1937), on the other hand, derived his orchestration directly from the Schandert edition. In this study I argue that Ashkenazy offers “corrections” to his predecessors, Ravel and Stokowski, whose orchestrations differ—at times radically—from Mussorgsky’s autograph. This dissertation thus will explore the significant features of Ashkenazy’s orchestration in relation to the urtext edition by comparing it to the orchestrations of Ravel and Stokowski. In an age of attempts to present “authentic” versions of past music, Ashkenazy’s orchestration provides an authenticity that other orchestrations lack. Ashkenazy’s orchestration of Pictures at an Exhibition provides conductors an alternative performance option that is both effective …

Installation and Manufacturing of Photovoltaics: an Assessment Using California and New York (open access)

Installation and Manufacturing of Photovoltaics: an Assessment Using California and New York

Renewable energy studies are becoming increasingly important as world energy demand rises and current energy sources are increasingly questioned. Solar photovoltaics (PV) are the focus of this study as a renewable industry still in its infancy. This research examines the geography of solar panel installation and manufacturing from 2007 to 2010 in California and New York. California is the larger of the two markets and has implemented more policy support; programs that appear to have increased the pace of installations, reduce the size of the subsidy, and help lower total costs. Similar trends are observable in New York. US based companies are still making solar panels, but foreign competitors, most notably from China and Mexico, are capturing an increasing share of the market.

Using Pre-session Mindfulness to Improve Therapy Presence (open access)

Using Pre-session Mindfulness to Improve Therapy Presence

While a significant amount of research illustrates the positive effects of therapists’ use of mindfulness, few studies have addressed whether therapists’ mindfulness actually improves psychotherapy outcomes. Additionally, no existing research has examined whether therapists’ use of a mindfulness exercise immediately before meeting with a client could also have a positive impact on the following session. The purpose of this study was to test whether engaging in a centering exercise 5-10 minutes before a session could have a positive impact on therapy, in particular on the therapists’ ability to remain present in session. Results indicated that the trainee therapists did not report changes in mindfulness after the brief mindfulness training program. Results also indicated that completing the centering exercise before a session did not appear to impact client ratings of therapeutic presence and session outcomes. The results suggest that more intensive training in mindfulness may be necessary to impact psychotherapy outcomes.

Music of the Spheres: Astronomy and Shamanism in the Music of Urmas Sisask (open access)

Music of the Spheres: Astronomy and Shamanism in the Music of Urmas Sisask

In 1619, Johannes Kepler published his magnum opus Harmonices mundi in which the astronomer derived distinct pitches and scales for each known planet in the solar system from calculations of various aspects of their orbital motions. This was the first theoretical realization of the ancient tradition of musica universalis (also called musica mundana), or music of the celestial bodies. It was not until the Estonian composer Urmas Sisask (b. 1960) began his compositional career by deriving his own “planetary scale,” however, that the theoretical musica universalis came into audible existence. Sisask’s work represents a distinctive musical voice among today’s choral composers, and although he is steadily gaining attention for his unique compositional style, only limited information exists about the specifics of his background, his interest in astronomy and shamanism, and the subsequent influence these interests have had on his choral music. At once traditional and modern, he bridges the gap between ancient Estonian folk song and the present. Through an application of exotic techniques including extreme repetition, ritualistically driving rhythms and sudden changes in timbre and texture; coupled with his own peculiarly crafted “planetary scale,” Urmas Sisask has created a completely unique body of work which is examined in this …

Acculturation and Depression in Older Mexican American Adults: the Role of Social Support (open access)

Acculturation and Depression in Older Mexican American Adults: the Role of Social Support

Despite socioeconomic disadvantages, less acculturated Mexican Americans tend to exhibit better mental health than their more acculturated counterparts. However, in the case of older Mexican American adults, research has demonstrated the opposite to be true (Gonzalez, Haan, & Hinton, 2001). A variable of interest potentially responsible for this difference is social support. Thus, the current study proposed to investigate the mediation and moderation effects that social support has on the relationship between acculturation and depression in older Mexican American adults age 60 or older. Data from the Health and Retirement Study (HRS) was analyzed. Results showed that the mediating effect of contact with one’s children (-.109*) and the moderating effect of total social support and contact with one’s children (-.127*; -.103*) were statistically significant in the relationship between acculturation and depression. Although these effects are small they may still hold important implications for better understanding this population.

Teacher Educators: What Motivates Them to Choose Academe? (open access)

Teacher Educators: What Motivates Them to Choose Academe?

Currently, there is a shortage of professors preparing personnel to teach in high need areas (e.g., special education, English language learners) at institutions of higher education (IHE). The purpose of the present study was to examine the motivations or influencers that impelled individuals to pursue careers in IHEs as professors in personnel preparation. Data were collected using Motivations for Choosing Academia as a Profession (MCAP) and a 10-item Big Five Inventory (BFI-10). Two hundred eighty-nine professors of education representing the four U.S. census regions participated in the present study. The MCAP is a 25-item instrument designed to measure retrospective motivation of faculty decisions to enter the professoriate. The development of the MCAP is described and an exploratory factor analysis was employed to examine the psychometric validity of the instrument. Three factors emerged and implications are discussed. Data were analyzed using logistic regression with the dichotomous outcome variable being the area of education in which the professor works (i.e., general or special education).

Data Envelopment Analysis: Measurement of Educational Efficiency in Texas (open access)

Data Envelopment Analysis: Measurement of Educational Efficiency in Texas

The purpose of this study was to examine the efficiency of Texas public school districts through Data Envelopment Analysis. The Data Envelopment Analysis estimation method calculated and assigned efficiency scores to each of the 931 school districts considered in the study. The efficiency scores were utilized in two phases. First, the school district efficiency scores were combined with school district student achievement to evaluate effectiveness with efficiency. A framework was constructed to graph the scores on an x-axis of student achievement scores and a y-axis of efficiency scores to further illustrate the data. The framework was evaluated with the full statewide sample and with school districts categorized into similar peer groups. Then, using variables selected from related scholarly literature, a regression analysis identified which factors impacted school district efficiency statewide. The non-discretionary variables included in the study were total student enrollment, the percentage of non-white students and the percentage of economically disadvantaged students. The discretionary variables selected included the teacher-to-student ratio, teachers’ average years of experience, the percentage of teachers with master’s degrees and the average teacher base salary. Amongst the seven factors selected for regression analysis, five statistically significant variables were identified as impacting statewide school district efficiency. All …

“Sounds for Adventurous Listeners”: Willis Conover, the Voice of America, and the International Reception of Avant-garde Jazz in the 1960S (open access)

“Sounds for Adventurous Listeners”: Willis Conover, the Voice of America, and the International Reception of Avant-garde Jazz in the 1960S

In “Sounds for Adventurous Listeners,” I argue that Conover’s role in the dissemination of jazz through the Music USA Jazz Hour was more influential on an educational level than what literature on Conover currently provides. Chapter 2 begins with an examination of current studies regarding the role of jazz in Cold War diplomacy, the sociopolitical implications of avant-garde jazz and race, the convergence of fandom and propaganda, the promoter as facilitator of musical trends, and the influence of international radio during the Cold War. In chapter 3 I introduce the Friends of Music USA Newsletter and explain its function as a record of overseas jazz reception and a document that cohered a global network of fans. I then focus on avant-garde debates of the 1960s and discuss Conover’s role overseas and in the United States. Chapter 4 engages social purpose and jazz criticism in the 1960s. I discuss Conover’s philosophy on social responsibility, and how his contributions intersected with other relevant discourses on race on the eve of the civil rights movement. I argue that Conover embodied two personas: one as jazz critic and promoter in the United States, and the other as an international intermediary. In chapter 5 I …

Texas Principals’ Perceptions of Professional Development Provided By the Local School District

The purpose of this study was to investigate the perceptions of Texas principals as to the degree to which their local school districts are meeting their ongoing professional development need. The study was conducted to analyze and describe the survey and interview responses of Texas principals as to their perceptions of the degree to which their local school districts provide learning experiences aligned with their needs. Texas principals’ perceptions regarding the characteristics of important and meaningful professional learning experiences were explored. The study included an analysis of the extent to which Texas principals perceive that the learning opportunities they are provided adequately meet those needs. Additionally, various factors influencing principals and their perceptions were examined. These factors included type of school, school setting, school system size, characteristics of students, and characteristics of the principals. The perceptions of school district staff development administrators were analyzed regarding topic importance, topic provision by the local district, and the usefulness of those topics. Finally, the perceptions of the principals and the staff development administrators were compared. Thirteen school districts participated in this study. Of the 273 principals surveyed, 155 completed the survey, yielding a return rate of 56.8%. One campus principal from each of …

Affective Forecasting: the Effects of Immune Neglect and Surrogation (open access)

Affective Forecasting: the Effects of Immune Neglect and Surrogation

Studies of affective forecasting examine people’s ability to predict (forecast) their emotional (affective) responses to future events. Affective forecasts underlie nearly all decisions people make and the actions they take. However, people engage in systematic cognitive errors when making affective forecasts and most often overestimate the intensity and duration of their emotional responses. Understanding the mechanisms that lead to affective forecasting errors (e.g., immune neglect) and examining the utility of methods for improving affective forecasting errors (e.g., surrogation) can provide highly valuable information for clinicians as they assist clients in determining their goals both for therapy and for life. The first purpose of the current study was to determine if affective forecasting errors due to immune neglect lead to misjudgments about the relative emotional impact of minor versus moderate negative experiences (i.e., trauma severity). The second purpose was to examine the utility of surrogation for improving affective forecasts. Potential interaction effects between these two variables were also examined. The current study utilized a 2 (Trauma Severity: minor, moderate) X 3 (Prediction Information: surrogation information only, simulation information only, both types of information) experimental design. Undergraduates were recruited via the SONA system and randomly assigned to one of the six experimental …

Morality and Mortality: the Role of Values in the Adoption of Laws Governing the Involuntary Removal of Life Sustaining Medical Treatment in Us States (open access)

Morality and Mortality: the Role of Values in the Adoption of Laws Governing the Involuntary Removal of Life Sustaining Medical Treatment in Us States

Disputes between patients and providers regarding life-sustaining medical treatment (LSMT) are universal across all U.S. states, yet policies regarding these disputes differ significantly. This dissertation determines that all 50 states have advance directive laws that protect a patient’s right to refuse LSMT even when a healthcare provider objects, yet only some states have policies that protect the patient’s right to choose to continue LSMT when a healthcare provider objects (a dispute known as medical futility). Some states have pro-patient laws that protect the patient’s right to make the final decision, while other states have enacted pro-provider medical futility policies that explicitly grant the provider authority to remove LSMT against the patient’s wishes. Finally, in one state, the law delegates the final decision to a third-party: institutional healthcare ethics committees. This dissertation studies the innovation and adoption of these 17 state medical futility policies, examining the theory that values determine both whether the state adopts a medical futility policy as well as what type of medical futility policy a state will adopt- as the policy actors that represent these values: policy entrepreneurs and interest groups. A comparative case study of successful third-party policy adoption in Texas contrasted against a failed effort …

Shaping Relations: a Media Framing Analysis of Japan-us Affairs in the Era of Japan (Sur)passing (open access)

Shaping Relations: a Media Framing Analysis of Japan-us Affairs in the Era of Japan (Sur)passing

The relationship between Japan and the U.S. has endured contention since the beginning of the millennium, but the two countries remain allies. This quantitative and qualitative content analysis examines the print coverage of two controversies in Japan-U.S. relations: the sinking of a Japanese fishing trawler and the controversy surrounding the Futenma base. By applying the theoretical framework of media framing, the research examines four U.S. newspapers and one Japanese newspaper while considering the two corresponding geopolitical periods: Japan (sur)passing. By coding each article for predefined framing categories, the research found in the era of (sur)passing, the application of the mea culpa and responsibility frames mirrored the geopolitical dynamic of the time. However, the reconciliation frame, created by the U.S. newspapers’ use of elite news sources in the period of Japan passing, went against the scholarly interpretation of the period, and instead focused on a positive bilateral relationship in order to influence public opinion.

Emotional and Cognitive Coping in Relationship Dissolution (open access)

Emotional and Cognitive Coping in Relationship Dissolution

Romantic relationships are important for social development and can impact an individual’s functioning both positively and negatively, especially when the relationship breaks up. Emotional and cognitive coping strategies including emotion approach coping, avoidance, and rumination and variable response to expressive writing intervention were examined in relation to post-dissolution distress. Undergraduate participants randomized into two groups completed measures of cognitive and emotional coping variables and global distress, with the experimental group completing a three-session expressive writing protocol. Writing samples were rated for processing mode, or the degree of vague general statements. Avoidance and rumination demonstrated significant cross-sectional associations with Time 1 distress controlling for demographics and characteristics of the former relationship. Gender moderated the relationship between rumination and distress. Using a matched sub-sample, the groups did not differ on emotional coping variables or distress. Results demonstrate the importance of examining emotional coping strategies in conjunction with relationship dissolution.

Proteomic Responses in the Gill of Zebrafish Following Exposure to Ibuprofen and Naproxen (open access)

Proteomic Responses in the Gill of Zebrafish Following Exposure to Ibuprofen and Naproxen

Non-steroidal anti-inflammatory drugs (NSAIDs) are among the most abundant environmental pharmaceutical contaminants. In this study, a proteomic analysis was conducted to identify proteins differentially expressed in gill tissue of zebrafish (Danio rerio) after a 14-day exposure to the NSAIDs ibuprofen or naproxen. A total of 104 proteins with altered expression as indicated by 2-dimensional electrophoresis were analyzed by liquid chromatography with ion trap mass spectrometry (MS/MS). A total of 14 proteins fulfilled our requirements for identification which included consistency among replicate gels as well as successful MS/MS ion searches with the MASCOT database. The most prominent feature of the differential protein expression observed after NSAID exposure was an up-regulation of proteins belonging to the globin family which are involved in the transport of oxygen from gills and availability of heme molecules required for synthesis of cyclooxygenase. Differential expression was observed at exposure concentrations as low as 1-10 µg/L indicating that altered gene expression may occur in fish subjected to environmentally realistic levels of NSAID exposure.

Caregiver Perceptions of Wandering Behavior in the Adrd (Alzheimer’s Disease and Related Dementias) Patient (open access)

Caregiver Perceptions of Wandering Behavior in the Adrd (Alzheimer’s Disease and Related Dementias) Patient

The dissertation examined family caregivers’ perceptions of wandering behavior after their loved one has been diagnosed with ADRD (Alzheimer’s disease and related dementias). Semi-structured in-depth face-to-face interviews of a convenience sample of 22 caregivers in the Dallas metropolitan area were conducted. Responses were analyzed using a grounded theory approach. The use of qualitative methods facilitated the study of how caregivers of a loved one with ADRD understood and explained in their own voice the wandering behavior associated with the disease and how their views of the behavior informed the caregiving process. In particular, this research examined why some caregivers tend to recognize wandering behavior as significant early on while the ADRD patient is still living in the home (and community) and modifications can be made to keep him or her there despite the behavior, and why some caregivers do not. Findings indicated that caregivers were concerned about the general safety of their loved one. Precautions were taken within the home for conditions related to frailty, but were much less likely to be taken to address wandering behavior and its negative consequences. Three groups of caregivers emerged: (a) those who primarily reacted to their loved one’s problem behaviors including wandering, and …

From Ritual to Art in the Puritan Music of Colonial New England: the Anthems of William Billings (open access)

From Ritual to Art in the Puritan Music of Colonial New England: the Anthems of William Billings

The manner in which Billings’s music contrasts with the Puritan musical ideal clearly demonstrates his role in the transition from ritual to art in the music of eighteenth-century New England. The tenets of Puritan worship included the restriction that music should serve primarily as a form of communal prayer for the congregation and in a secondary capacity to assist in biblical instruction. Billings’s stylistic independence from Puritan orthodoxy began with a differing ideology concerning the purpose of music: whereas Calvin believed music merely provided a means for the communal deliverance of biblical text, Billings recognized music for its inherent aesthetic worth. Billings’s shift away from the Puritan musical heritage occurred simultaneously with considerable change in New England in the last three decades of the eighteenth century. A number of Billings’s works depict the events of the Revolutionary War, frequently adapting scriptural texts for nationalistic purposes. The composition of occasional works to commemorate religious and civic events reflects both the increase in society’s approval of choral music beyond its nominal use in worship, both in singing schools and in choirs. With his newfound independence from Puritan ritual, Billings seems to have declared himself one of the United States of America’s first …
