I'm always crafting different ways to view the "every note can work over a dom7 chord" idea. I have quite a few of them at this point. But, for a few months I've been tying things together, from a theory aspect, with a number scales that flow from one to the other or are just a vehicle to open up the entire fretboard, but each still having their own drive behind the improv. The main idea is (in the case of A7) creating lines that flow from mixing A Mixo to A Lyd Dom to A H-W and back to A Mixo, or maybe walking backwards through the sequence, or maybe never reaching back to A Mixo again but also hearing how to exploit each one individually. Here's the vid... http://www.youtube.com/watch?v=1utjgFScgBE Now beyond this, I also view this from each the A7, C7, Eb7, and F#7. So, if we wanted to twist our thoughts around the theory aspect this clip is using: A Mixo, C Mixo, Eb Mixo, F# Mixo A, Lyd Dom, C Lyd, Dom, Eb Lyd Dom, F# Lyd Dom A H-W, C H-W, Eb H-W, F# H-W As well as some A Whole Tone (and derivatives) A little A Phrygian Dom too... all over a straight A7 chord. I guess you can think of it as looking INSIDE the (A7) chord, but the playing sounds OUTSIDE. I've always thought about this stuff as playing OVER the chord. Beyond that I'm just trying to play through this stuff freely. Not that this is a huge revelation, or it's that great of playing, or anything else as I'm sure a lot of people here have special ways of chopping things up for themselves and I know there are people here who can play rings around this type of stuff, I just thought I'd share.
