A valuable guide for composers and trombonists. It familiarizes composers with contemporary trombone techniques and shows how to put them to creative use. Furthermore it helps trombonists to view and employ their versatile instrument as a multi-functional sound generator.

Together with composer Michel Roth, Mike Svoboda explores what might today be called "the unlimited expansion of new performance possibilities": micro-intervals, multiphonics and the combination of the trombone sound with the human voice - all accurately described and illustrated with many annotated music examples.
