Unless grad rec prefers it in bullet points, I would put them in paragraphs, possibly by grouping different achievements/activity by type. So one paragraph for sports, one for volunteering, one for any misc competitions etc. You don't need to go into what the activity taught you but detaching what you did and what awards you got for your efforts is important.
I'd be inclined to place music grades in achievements over activities because they represent the attainment of a level of skill/knowledge. What do you think?
