I've read few articles about it, but none of them seem to help me with this problem.
Let's say we have a song in certain key - which harmonica should I choose? Let me give you an example, we have a song "She caught the Katy":
I have tried many keys (C, E, F - that's all I have) and none of them fit. Any Ideas?
And is there any general method of choosing harmonica key basing on key of the song?
Thanks for any help!
