Henglu Yao is a contemporary Chinese composer who has composed a large number of intermediate piano works using a blend of traditional Chinese musical elements and modern Western compositional techniques. This dissertation uses Yao's Mikrokosmos from Chinese Nationalities, composed in 2017, to conduct a comparative study with last three volumes of Bartók's Mikrokosmos, exploring the folk music characteristics of the two composers' respective nationalities. Furthermore, this dissertation observes the musical and technical similarities and differences in modern piano teaching repertoire, especially those that are influenced by their respective national musical traditions. The comparison and elaboration of the two composers' use of modern harmony, modern rhythms, imitation of folk instruments, and application of mathematical concepts are detailed in the text. In addition, I provide pedagogical suggestions on the challenges of practicing the contemporary music in Yao's Mikrokosmos, including aural training, asymmetrical rhythmic training, and phrasing practice. Lastly, I provide detailed suggestions for certain pedaling and fingering aspects with which students may struggle.

Florence Price (1887–1953) was one of the most important African American woman composers of the early twentieth century. Price's music is known for combining techniques of Western art music with elements of the African American musical heritage. Although Price composed many works for piano, from large virtuoso pieces to characteristic miniatures, this study will address only her Piano Sonata in E minor. The purpose of this study is to analyze this sonata and discuss her compositional techniques and musical style as a combination of African American elements and Classical European procedures, combined and coordinated yet remaining in tension. Traditional European harmony, tonality, and form are successfully combined with African American characteristics: pentatonic scale, spirituals, syncopations, repetition, and dance rhythms. Indeed, Price's work is a considerable achievement, and she is one of the important African American women composers who should be better recognized today.

Bohuslav Martinů's "Concerto for Oboe and Small Orchestra" is one of the most frequently played pieces in the oboe repertoire. For this reason, it is often played with the piano reduction instead of the orchestra in oboe recitals. However, the existing piano reductions include many errors and discrepancies from the orchestral score, misrepresent the orchestration, sometimes fail to make the oboe entries clear, and tend to be unplayable for pianists. Moreover, the scores were published after the composer's death without him supervising the final editing. I have prepared a new, playable piano reduction to represent the orchestration more faithfully and help pianists work with their soloists more easily. Based on the work of Martin Katz, a prominent collaborative-pianist, I establish four principles for creating a new piano reduction. After scrutiny of the deficiencies of existing piano reductions, I suggest solutions for making the passages in question practical and bringing out the leading voices clearly so that the soloist can join in as easily as playing with an orchestra. To aid in reflecting the orchestral texture that Martinů created, I include abbreviated instrument names in many passages to help pianists to understand how to create balance. I have changed some passages …

A flexible nanofibrous PVDF-BaTiO3 composite material is prepared for impact sensing and biomechanical energy harvesting applications. Dielectric polyvinylidene fluoride (PVDF) and barium titanate (BaTiO3)-PVDF nanofibrous composites were made using the electrospinning process based on a design of experiments approach. The ultrasonication process was optimized using a 2k factorial DoE approach to disperse BaTiO3 particles in PVDF solution in DMF. Scanning electron microscopy was used to characterize the microstructure of the fabricated mesh. The FT-IR and Raman analysis were carried out to investigate the crystal structure of the prepared mesh. Surface morphology contribution to the adhesive property of the composite was explained through contact angle measurements. The capacitance of the prepared PVDF- BaTiO3 nanofibrous mesh was a more than 40% increase over the pure PVDF nanofibers. A comparative study of dielectric relaxation, thermodynamics properties and impact analysis of electrospun polyvinylidene fluoride (PVDF) and 3% BaTiO3-PVDF nanofibrous composite are presented. The frequency dependent dielectric properties revealed micro structural features of the composite material. The dielectric relaxation behavior is further supported by complex impedance analysis and Nyquist plots. The temperature dependence of electric modulus shows Arrhenius type behavior. The observed non-Debye dielectric relaxation in electric loss modulus follows a thermally activated process which …

One of the most recognized icons of Mexico is the mariachi moderno tradition, which in the global popular imaginary, is associated with nostalgic, humorous, and emotional songs of love, heartache, death, drinking, and place. Inseparably fused to tequila and the historic charro figure, mariachi moderno completes a symbolic trinity of hetero-nationalist culture, conveyed within a popular imaginary of authentic mexicanidad (Mexican-ness). For mariachis and aficionados in Mexico, performative hypermasculine machismo acts as a perceptual baseline, structuring modes of feeling that signify an experience of authentic nationalist musicality This process is musically constructed in an incorporation of bodily movement, instruments, sound timbres, and symbolic clothing, simultaneously gestured with a heavy male-accent fusing an experience that feels genuinely Mexican. This reflexive signification is a consequence of the lived experience, shared dispositions, and competencies learned in the habitus, constituting real and imagined notions of hetero-nationalist culture. I refer to this musical semiosis as mariachismo, a neologism describing an intersubjective experience of machismo-infused mariachi subjectivity, ritualized through repeated gestures of sound, lyric, and corporeality. The semiotic power of mariachismo is most potent for subjects enculturated to Mexico's hetero-nationalist culture, shaped by popular imaginaries operationalizing gender and mexicanidad, connecting the two, making them feel unquestioned, …
