Paganini's 24th caprice still remains to this day one of the most celebrated themes in classical music history. Many composers have used this theme to create variations and each composer attempted to produce stylistically unique variations on this piece. Hamelin's Variations on a Theme of Paganini stands out because his piece incorporates musical borrowing and many different composers' styles. His variations integrate music from different centuries, using pastiche and musical borrowing from figures such as Beethoven, Liszt, Brahms, Chopin, and Rachmaninoff. More provocatively, Hamelin's variations reach outside of Classical music, even adopting elements from salsa and friska. The spectrum of composers and styles included in this set are so radical and shocking that it creates a parody of not only Paganini's theme, but also the tradition of theme and variation pieces it has inspired. Due to its multiple variations juxtaposing extremely different styles, Hamelin's Variations on a Theme of Paganini presents the listener with a musical puzzle that is designed to invoke surprise. The juxtapositions of extremely different styles in these variations create disjointed variations with polystylism. The polystylism in this work diversifies his variations, while unifying these seemingly unbalanced movements through broad musical references. As such, both performers and listeners stand to benefit from a detailed, critical examination of the piece. I consider not just the musical sources themselves, but also the ways in which they interact, paying close attention to Hamelin's use of parody and humor.

The American composer Charles Ives is well known for musical quotation/borrowing: composing music with or from pre-existing musical sources, such as folk tunes, hymns, chants, or other composers' works. His Third Violin Sonata is one of few works that used his unique technique of cumulative setting with only hymn tunes. For analysis of his instrumental music, the text of the hymn tunes is generally disregarded, as the compositions are for instruments. Ives' Third Violin Sonata is challenging to understand in comparison with other violin sonatas, because it lacks information such as titles and subtitles. Even though Ives never mentioned the piece's meanings or extramusical meanings, almost all the elements of the piece indicate hope as a common theme. This dissertation examines which hymn tunes were quoted in the piece, gives the meanings of the hymn tunes, and discusses how Ives uses these tunes as themes with textual meanings. The study includes a brief life of Ives and his historical circumstances and presents a brief musical analysis. The research should give a better understanding of the piece to performers and others curious about it.
