Last week the Zoom group tried to learn a song in the key of B maj. It's a bit of a "weird" key for me, but I worked on it. I downloaded a backing track for the song "Unforgettable" in the B major key.
It seems really helpful, especially to me as an ear player, to play songs in different keys just to get the "feel" of playing in that key. If you'd like to try this, and especially if you don't read music (like me!), I'm posting the backing track along with my pdf version of the tabs for that song. Jump in and give it a try!
FYI, my tab method is, for example: 4 (blow hole four), -4 (draw hole four), 4* (blow hole four, slide in), -4* (draw hole four, slide in).
BTW, the track has a four bar intro. Don't be fooled!
Good luck!
