I've been practicing with the pedal steel and guitar voices lately, and when using the pitch bend wheel and playing chords both with the left hand at the same time, I've been finding out how C & D together make a D7 chord, but Bb and C together make a Cm chord. To make a two fingered C7 chord, you need to play C & B together. Doesn't make sense, but that's the way it is.
Anyway, these one and two finger chords can free up a pinky for the pitch bend wheel.
