This document is a compendium of the materials that are housed within the special collections donated by Thomas Everett. In August 2016, the Arizona State University School of Music, through the efforts of retired Professor of Trombone Douglas Yeo, received a donation of materials from Thomas Everett, founder of the International Trombone Association and retired director of bands at Harvard University.

This donation contains published and unpublished music, numerous letters, and various drafts of his book, An Annotated Guide to Bass Trombone Literature. Over the course of two-and-a-half years, the donation was catalogued for the university by the author. Materials from the donation were sent into public circulation or sent into special collections within the ASU School of Music Library.

This thesis proposes an augmentation of the Complete Method for Trombone by Jean Baptiste Arban. Although it is widely considered one of the leading trombone method books in the world, a thorough consideration of the demands of most performed solo literature today reveals serious shortcomings in the Arban Method for preparing trombonists to encounter such demands as meter and rhythm, keys and tonalities, range and endurance, clefs and F-attachment usage. This thesis thus proposes additions for a new version of the Arban Method that better aligns with the playing demands of the most performed solo literature today, as compiled by the International Trombone Association Journal since 1972.
