Thanks everybody - I'm pretty useless when it comes to all this tech. stuff!

A particular song I'm trying to do is played in D "uncapoed" and I put a capo on the first fret to suit my voice. Does this mean its then in D#/Eb? If so what harmonica would be needed????

The harmonica player in this instance is a novice so I don't think she'll know (also she's my wife!!!)
