Like gesture I have been coming back to practicing the blues lately, and I’m particularly interested in what harmonic modifications one can do to add a little more ‘volume’ and ‘density’ to the changes, especially when playing unaccompanied or just with bass or in a trio.
In the clips below Kurt is demonstrating some awesome unaccompanied playing and I’d be really interested in what’s going on harmonically.
I assume that he uses a lot of approach chords like diminished, secondary dominants and triton subs. While I’ve been using that concept to some success for Standards, I have a hard time doing the same thing with the blues, as in most cases the secondary dominants are identical to the preceeding chord anyway (I hope you get what I mean...) Any suggestions regarding specific extentions of voicings to use, or other substitution devices? I’m especially referring to Kurt’s playing in the second clip.
