Major Chord and Diamond Rose

A bit of an over view on Major Chord. He grew up on a bad street in New Colt City (you try thinking of a horse pun for New York) though he turned out just fine, maybe a little playerish. He owns a music shop in Ponyville and lives with his teenage brother Vocal Chord. Just thought that would be necessary.
