adventure Character name and details

[Steel Accord 6,658]

So I am writing a story and about to introduce a character that will become an ally and friend to the protagonist.

 

He is meant to represent the musical aspect of the brony fandom. He is an earth pony skilled in a number instruments as well as a good singer. He is really passionate about music and is also a bit of a spaz. Think of him like a cross between Mandopony, Mic the Microphone, and Vinyl Scratch.

 

Apart from a name, what should this guy's color scheme and cutie-mark be?
