One thing that I would recommend any aspiring arranger do in the early years of writing charts is to solicit opinions from the players on the parts you give them to play.
In the early days of my arranging days, I used to ask drummers alot of questions about how my parts were written for them. The biggest lesson I learned is that drummers generally want a simple part – but with enough information so that they can fit in with what the band is doing. They want a part that will give them what they need so that they can execute the part correctly.
