My suggestion would be to pick up a Hohner Pro-Harp in the key of D. I find that the easiest key to get the sweet bluesy sounds out of. Also, you will find a lot of music in the keys of G & A, so you can accompany both with your C & D harp playing cross-harp 2nd position... In my opinion, these are the 2 best keys to start with...any suggestions? Comments??? Rick "Cottonmouth" Johnson
