Creating band parts from piano music
Over the weekend, I, a rank novice both with MuseScore and with music itself, having ended my career as a bass clarinetist in the early days of the Kennedy administration, successfully, with some help from this forum, input the piano score for "The Carlisle Indian School March" into MuseScore. Now, I would like to change it from being a piano piece to being music for a marching band as Dennison Wheelock intended when he wrote it in 1896. However, I don't have a clue as to how it should be done. I suspect that it needs to be "arranged" for clarinets, trumpets, trombones, etc. but don't know how to do that. Is there a program that takes piano music and creates parts for various instruments from it? Or, must one learn a lot about music composition and do this manually?
Thank you for your help. The fruits of my labor to date can be found at: http://www.youtube.com/watch?v=iRTURifvbxQ
