The Greatest Writing Challenge Ever

Trying to describe what an arrangement is was the greatest writing challenge that i have ever faced. And it force me to get really clear on stuff that i i have a lot of skill with and a lot of familiarity with, but not a lot of clear lang for. One of the things that arrangement contains is tempo. You can write a song, and have a written song taand has no tantonts, and then you immediately have to give it one 20 b p m and you're good to go. Everybody will dance.
