I'm trying to learn how to play mandola and have been tuned C-G-D-A. I tried playing a few fiddle tunes I know how to play in C and D on guitar, and D on mandolin -- St Anne's Real and Whiskey. I found than on the mandola playing in C resulted in much easier fingerings and just sounded better. Realizing that I need to play these songs in D in a jam, I put a capo and played them. I found it was much easier to play the mandola this way. I've never used a capo on my mandolin, but have to say I find the mandola feels like it was designed for playing in C (over D). I'm curious what folks recommend.
