Question

Alright I usually play in DAD but have decided to venture out of my comfort level and go CGc and DAa. But I only have music for DAD, so will I have to start looking for sheet music for these other tune?

I was wondering where the heck is the small c or a or for that matter d and saw the small letters are one octave less then the D, C or A  and it doesn't sound bad.

Anyway if everyone is falling in the floor laughing just remember you had to start somewhere to learn too
