I’m writing for a group that has 3 (jazz/latin-oriented) percussionists, each of whom may choose to play any of 3 parts I’m laying out. I’d therefore like them to all have the same, single percussion part that has (in both the score and parts) a multi-line staff that has triangle on the top line, shaker on the 2nd line, and congas (high low) on lines 3 and 4, with all 4 parts completely independent of each other (ie. each line with its own, uncombined stems). I was experimenting with creating a Percussion Kit but this seemed to create complications. Does anyone kindly have a quick explanation for my best course of action to create this? Thanks in advance!
