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.

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.
