This manual, Training Circular TC 1-19.30 Percussion Techniques July 2018, Percussion Techniques, describes common percussion instruments used by Army bands, and provides performance techniques for each instrument. This publication is a reference guide to be used when needed. The principle audience for TC 1-19.30 is all skill level 1-4 Soldiers holding military occupational specialty (MOS) 42R or 42S, with the additional skill identifier (ASI) of 9M, 9N, 9T, 9U, 9V, 9X, 9H, and 9K that do not double on another marching band instrument, and for trainers and musical supervisors. This publication serves as the primary reference for both resident and nonresident percussion techniques instruction presented to Soldiers, noncommissioned officers, warrant officer bandmasters and commissioned officers. Trainers and first-line supervisors should ensure Soldiers holding ASI of 9M, 9N, 9T, 9U, 9V, 9X, 9H, and 9K (skill level 1-4) have access to this publication. It should be made available in the Soldiers' work area, unit learning center, and unit libraries. As this publication is a guide, and as all possible situations and eventualities cannot be foreseen or covered by the manual, great reliance must be placed upon the application of sound judgment and common sense by all members of a music performance unit (MPU). In situations not covered by this manual and where doubt arises as to the proper action to be taken, the individual must consider their mission and apply sound judgment in making the required decision(s). TC 1-19.30 applies to the Active Army, the Army National Guard, the Army National Guard of the United States, and the United States Army Reserve unless otherwise stated. The proponent of TC 1-19.10 is the United States Army School of Music.
