I think a lot of time we don't have to make accommodations because music does that naturally, (less technical parts for some, different level ensembles, Instrument placement based on cognitive/physical abilities, choosing S/E literature based on their ability as opposed to their age, etc.).
we've seen kids in wheelchairs on the marching field, overlays and colored paper for dyslexia students, and I had admin observe my class because I had twins that could fully function in my rehearsal, (3rd band) but couldn't sit still for 10 seconds in their core classes. Truth be told, these kids needed to be working with their hands and I offered that with by the nature of the kids playing Flute/Percussion. I think band does a great job of working around kids individual learning. At the same time, the world can't always accommodate that and maybe people should choose careers like they get placed on an instrument. If you are ADHD, accounting probably isn't for you but fast paced sales might or customer service where things change frequently might be.
