Business Name?

Help! We are having a little big dilemma here. Did you notice our new website (under construction still)? Well we would like to start teaching music around Layton. We have a graphic designer friend helping us come up with a logo/brand for our soon to be little music studio. She is wonderful! (Go here to view her husband's photography website that she designed!) However, we are having the hardest time coming up with a name for our business. We want it to include Dimond. We want it to be general/broad enough so that in twenty years it still sounds good. We want it to incorporate music, obviously. Teaching, but also performing. Piano, drums and guitar. Also we buy/sell and fix instruments. What brilliant name incorporates all of these aspects of our future business?? Dimond Music Studios? Our friends' suggestion; Key of D. Plain Dimond Music? Please, please help us brainstorm!
