More than 200 compositions have been written for solo trombone and organ since the nineteenth century, including contributions from notable composers such as Franz Liszt, Gustav Holst, Gardner Read, Petr Eben, and Jan Koetsier. This repertoire represents a significant part of the solo literature for the trombone, but it is largely unknown to both trombonists and organists. The purpose of this document is to provide a historical perspective of this literature from the nineteenth century to the present, to compile a complete bibliography of compositions for trombone and organ, and to determine the current state of performance of this repertoire. This current state of performance has been determined through an internet survey, a study of recital programs printed in the ITA Journal, a study of recordings of this literature, and interviews and correspondence with well-known performers of these compositions. It is the intention of this author that this document will serve to make the repertoire for trombone and organ more accessible and more widely known to both trombonists and organists.

In 1988, Jean Guillou composed Hyperion on a commission from the French oil company, Société Nationale Elf Aquitaine, to celebrate its discovery of oil. He developed this theme of fire using his imagination, European philosophical concepts, and various myths. As with Messiaen, rhythm becomes a significant element in Guillou's organ music to convey a heightened dramatic story of an exaltation of fire and to represent the fourth movement of "Agni-Ignis." For aspects of rhythmic structure, I developed new methodology to analyze rhythm in six sections of "Agni-Ignis." Guillou uses experimental rhythmic techniques such as rhythmic subdivision, cycling, rhythmic ostinato, durational contrast, and rhythmic crescendo to build the musical structure of the piece. Among them, the primary subdivision of 16th-note groups organizes throughout the piece as a cyclic theme to convey the powerful and vivid mood of fire. This rhythmic group creates many pitch patterns as thematic transformation to provide both rhythmic and harmonic complexities. The two types of rhythmic ostinato, which is variable and invariable type, juxtapose below the manual's skillful rhythm to provide variety and unity. The other notable features of rhythm appear at the border of each section, such as rhythmic crescendo, durational contrast, 32nd-note groupings, rest and …

Alexander Grechaninov was one of the most important composers of the late Russian Romantic School. By the second half of the twentieth century he remained one of the few living composers who continued the traditions of the great Russian Romantic masters, such as Tchaikovsky and Rimsky-Korsakov. He is primarily known for his liturgical works, which are truly masterpieces of this genre. Because many of his instrumental works remain unpublished, particularly the chamber works, they continue to be undeservedly ignored in the concert hall. Grechaninov's unpublished works for clarinet include Septet for Clarinet, Bassoon and String Quintet, Op. 172a, Serenade for Clarinet and String Orchestra (without opus number), and Sonata No. 1 for Clarinet and Piano, Op. 161. This project not only brings to light Grechaninov's unpublished clarinet works, but also emphasizes the importance of his published clarinet pieces which have to date been forgotten, especially in the United States. The writer prepares a performance edition of the Sonata No. 1, Op.161 from Grechaninov's original autograph manuscript which is held in the New York Public Library's Toscanini Archives. After a brief introduction, the document describes Grechaninov's biography, including his historical and societal background, compositional growth throughout his career, and outside influences …
