[Harp-L] Playing in majors/minors

[todd allen <soundguyaudition@xxxxxxxxx>]

I'm still having a hard time wrapping my head around what harp to use when the 
band calls out a song in minor's or major's.For example Ohio by Neil Young in D 
minor, or Dancing in the moon light by Van the man in F minor. I typically go 
right to cross harp (2nd position) for most everything we do, if that doesn't 
sound right I just go through every harp in my case until I find the key that's 
least offensive. I have looked at circles of fifths and other charts but don't 
get why  they just don't include majors and minors in the typical harmonica 
position charts, I guess I just don't get it. do they even relate to the key of 
harp or is it more about the notes you play?
