In 1939, during his studies at the Eastman School of Music, John La Montaine (1920-2013) composed a Scherzo for four trombones. The Scherzo was revised more than 60 years later, becoming the third movement of a three-movement trombone quartet completed in 2001. Interestingly, the same Scherzo subsequently appeared in two of his later works: first the final movement of his Piano Concerto No. 4 Op. 59 (1989) and 12 years later as the final movement of a three-movement Trombone Quartet. The thesis presents a detailed account of the compositional history of the Scherzo, its connection to the first two movements, and a performance edition of the Scherzo based on my collaboration with the composer between for five years from 2003 to 2007.
