In Appalachian Spring, Aaron Copland creates a unique tonal environment. Although often considered a tonal work, it contains many non-functional progressions and techniques that belie common-practice norms. The entire first movement, and sections of other movements contain no harmonic motion, in part because tonic and dominant chords sound together as a single sonority. In other movements, harmonic motion, in part because tonic and dominant chords sound together as a single sonority. In other movements, harmonic motion is increased by shifts to third-related keys, and non-functional progressions. Also, the variations on the melody "Simple Gifts" never employ common-practice techniques. Through the free use of materials, Copland creates an individualistic example of tonality in twentieth-century music.

The Crucifixion, a composition for three vocal soloists, four-part mixed chorus, and instrumental ensemble, is a setting of passages taken from the four Gospels of the Holy Bible. It describes the mocking of Christ and includes the Seven Last Words of Christ on the cross. It uses serial technique in the structuring of pitches and rhythm. Special attention is paid in designing and combining pitch and rhythm to create monophonic, homophonic and polyphonic textures. Besides traditional performance techniques, the work employs some modern vocal and instrumental techniques.

Ka is a one movement composition for chamber orchestra consisting of three sections. The work's harmonic, melodic and rhythmic materials are derived from the Chinese I Ching ("Book of Changes"). The middle section was composed with the aid of a computer program written by the composer. The program generated the interval sequence arrays forming the harmonic basis for the piece. Ka is scored for flute, oboe, B𝄬 clarinet, bassoon, French Horn, trumpet, trombone, three percussionists, violin, viola, cello and double bass. The score is 62 pages with a 39 page analysis preceding the score. Ka has a duration of approximately 10 minutes with no pauses between sections.

House in Heaven is a theatrical piece for five solo voices (one soprano, two mezzo sopranos, one baritone, and one bass), two trumpets, four French horns, one trombone, two flutes, two clarinets, two bassoons, string orchestra, vibraphone, timpani and a synthesizer which produces pipe organ sound. The composition consists of an introduction followed by a single act in three Scenes. The piece employs the cyclical device in engaging themes associated with particular characters. The texture grows from simple alternating dialogues to arias and, finally, to tutti passages in which all voices are combined to form a quintet, at the climactic point of the entire composition, which occurs at the end of the piece. The scenes depict imaginary events in a Church and at a flower garden. Rear-stage slide projections are used to project the scenes of these locations, and lighting is used to emphasize actions, characters and changes of scene. The singers also serve as actors. The duration of this work is approximately 20 minutes.

In mid-eighteenth-century France, a type of ensemble music was introduced for harpsichord and another instrument(s) in which the harpsichord part is completely written out, instead of a bass line with figures to be realized. Composers of this genre used the word "accompanied" in the tides or in the prefaces of their collections to describe the genre. This study examines the earliest examples of this genre, the works of seven composers, published in the 1740's, (Mondonville, Rameau, Boismoitier, Clement, Dupuits, Guillemain, and Luc Marchand), and compares the various styles of the written out parts, both harpsichord and additional instrument, to determine the nature of the word, "accompaniment."

Whereas conditions have existed for many centuries which served to exclude or marginalize female participation in music, many women have written compositions of musical worth sufficient to justify their contemporary performance. Although most women composers wrote works more fitting for the "salon" than for the concert hall at the turn of the century, Boulanger and Mahler are representative of the few women composers whose complex approach to art song fell within the mainstream of the genre. Many of their accompaniments attain a level of technical difficulty not previously found in women composers' writing. They offer an interesting comparison between nationalities and styles in that they both favored Symbolist texts. However, each represents a different side of the coin in her musical interpretation of Symbolism: Boulanger, Impressionism, and Mahler, Expressionism. In addition, even though their styles involve opposite musical expressions, they both show a strong influence of Wagner in their writing. This study includes background on turn-of-the-century music and musicians encompassing the role of art song among women composers. Symbolism is addressed as it applies to the poets selected by the composers, followed by information regarding the specific musical representation of Symbolist texts in the composers' art songs.

The musicians in E. T. A. Hoffmann's tales and essays demonstrate traits remarkably similar to those of shamans. Hoffmann uses the same imagery to describe the journey of the composer into the "realm of dreams," where he receives inspiration, as the shaman uses to describe the spirit world to which he journeys via music. Hoffmann was a major force in changing the 18th-century view of music as an "innocent luxury" to the 19th-century idea of music as a higher art. As a German Romantic,author, he subscribed to the idea championed by the Schlegels that true poetry is based on myth. In this thesis, Hoffmann's writings are compared with shamanic mythology to demonstrate a similarity beyond mere coincidence, without drawing conclusions about influence.

Riders to the Sea is a chamber opera in one act of approximately 40 minutes in duration. The single act is divided into six scenes that progress without pause. The vocal parts are comprised of 2 sopranos, 1 mezzo-soprano, 1 baritone, and an off-stage chorus of men's voices (tenor I, tenor II, baritone, and bass; two per part). The orchestra will be comprised of winds (1-1-1-1-1), brass (2-2-1-1), strings (2-2-2-2-1), piano, 2 percussionists, and tape, that will be used to provide a continuous background of surf and wind sounds. Authentic Irish folk songs are threaded throughout the work, generally functioning as a background element, while twentieth-century compositional techniques are utilized primarily for special effects.
