I'm trying to wrap my mind around playing with a guitar/harmonica and having both in the correct key ?
I'm not an amazing guitarist and the guy I jam with plays harmonica well but has 0 understanding of musical theory (i have 0.1 understanding). We play blues/blues derivative music, in E (cause it's the easiest) and he has a C-harmonica (and a G, and an E, but he prefers playing on the C because of the size of the holes or something...).
Now, conventional wisdom says to play an A harmonica in cross harp position, but I'll get to that in a moment. If we look at a C-harmonica, we have the following notes...

Which imo is perfect for blues in E - you have E,G, A, B D right by each other, so you can shuffle between all the adjacent notes on E pentatonic, and A and B next to each other on draw 7/8 so you can bend for the blue note there. And when I listen to recordings of ours it doesn't sound like he's out of key. http://www.box.net/shared/ltoza3elch .
Now if we look at an A-Harmonica's layout...
A C# E A C# E A C# E A
1 2 3 4 5 6 7 8 9 10
B E Ab B D F# Ab B D F#
I don't see why is this more suited to blues in E than the C harmonica?
