Like Carol H. and Lola M. have already said, this music store has a little of everything!
I was greeted right away upon entering the store, and wanted to do a little browsing around first before I asked for any help. This music store was like a mecca for sheet music! But I did a little perusing myself before asking for the piano Christmas music.
The friendly staff member brought me to where all the various Christmas music was. There was seriously anything and everything.... from beginning, intermediate, and advance... to Lorie Line holidays... to even John Denver Christmas! I found a wonderful book that had like 100 holiday songs -- perfect!
Again, as others have mentioned -- if they don't have what you're looking for they can order it.
And the music books/sheet music is not just for piano -- for so many other instruments as well. And every genre you could think of.
So I went to pay and when the clerk rang me up, he automatically started a "punch card" for me. Apparently... you get little punches for each $1, or so that you spend. And when your card is filled up, I think you get a $4 in-store credit. Cool! (I wasn't even expecting or thinking of that...)
And if you're a light rail rider... you can walk up from the stop at Camelback/Central! :)
