Basically, me and my composer friend have been arguing about this, so I wanted your guys' opinion.
My argument is that basically that composition is coming up with an original idea, and arranging is making a play upon an idea. Therefore, arranging cannot be composing. However, he's saying that since it's presenting music in an original way, it is composition since it is original in the sense that they're showing something old in a new light, like a new arrangement of an old song, like Caravan or Pachelbel's Canon.
I just wanna see what you guys think.
