\version "2.16.2"
%{
	LilyPond file definitions for Pipeband drumming scores.
	Primarily focused on Snare drumming,
	occasional bass or tenor scores should be possible.
	Especially with the use of an external eps file with flourishi symbols

	This file builds on work done by Simon Froger.

	Include by using :
	\include "[path]/lilydrum.ly"

	Music has to be put into :
	\new DrumStaff {
		\drummode {
		 [musique]
		}
	}
