This isn't really trumpet-related, but we don't have a general music disscussion area here on TM so I thought this is a pretty good place to ask my question. Anyways, I'm writting a piece for my schools symphonic band to play next year (hopefully) but I'm haveing some trouble writting the percussion parts. I'm not a percussionist, and I've never really even seen a percussion part enough to understand anything about it, so it's giveing me some problems. My main question is this, the whole piece starts off with a big timpani roll, but I have no Idea how to write that! I always figured if the piece called for a roll held out for 4 beats it would use a whole note, but that just has one hit being held out for 4 beats. So then I tried it with just a bunch or 16th or 32nd notes, it looks ok on the paper, but it sounds bad (maybe its just the midi that sounds bad, i don't know). So, if anyone could explain to me how to make drum rolls on finale2005, that would be the greatest thing ever and you would be my new hero.
