Familiar to conductors, orchestra managers, and music librarians, this classic sourcebook of information necessary to plan orchestral programs and organize rehearsals has been greatly expanded and revised. The fourth edition features nearly 6400 compositions that cover the standard repertoire for American orchestras (a 42% increase over the third edition), clearer entries, and a more useful system of appendixes. Included for the first time are entries from the American Symphony Orchestra League's OLIS repertoire database.
