Multiphonics is a technique that involves the creation of sound from both the embouchure and the vocal instrument.  This is a method book that moves the player step by step on how to produce two simultaneous sounds on the tuba or trombone.  The system is divided into steps that are designed to slowly introduce the player to the simple development of this technique.  Theory and practical applications are given as well as exercises.  

NB I am aware of the Yankee Doodle rhythmic augmentation to the melody and am working on correcting this error.
