what key of blues harmonica do i need for a 12 bar blues jam in e?

Answer 1

Play 2nd position (cross harp) on a C harmonica which will put you in the key of G, which is how most blues players use the diatonic harmonica.

Sorry..........just re-read your question. For the key of E (strictly speaking E minor) you need to play 5th position on a C harmonica.

Answer 2

I recommend A , C , Db , G

Also it is best to get a blues harp or a Marine Band harmonica for blues.

Answer 3

The Key of B my man and remember you can't do the Blues unless you do the booze
