OK, this is just a little thing for self-proclaimed "pentatonic box wankers" trying to break out of the box & the rut.* My thing here is just playing minor stuff down a 4th over Dominant chords. So over something in G, maybe over a G7, go up to where you usually play D stuff and play D minor things. Over an E9 vamp, stay right there at the 7th fret and play B minor stuff. Don't bend as much at first - try sliding into notes or playing without bending. Try out your minor pentatonic and dorian stuff (Santana riffs, etc.), and try skipping notes, playing every other note. Now, the reasons why are not important right now, but they are related to chord tones & another important cool thing, which is: over a I-IV-V playing Major pentatonic over the root (e.g. A7) and when it goes to the IV (D9) playing A minor pentatonic. It's the same thing. (Please see Decay-o-caster's excellent explanation of chord tones in this context in THIS thread) But thought of this way it can help in all kinds of contexts: Over any Dominant chord ("Bingo chord" - C7, B9, E7#9) play minor stuff based on the note "down a string" from the root. Over C7 play G minor stuff, over B9 play Eminor stuff, etc. So if you're playing some song that you can solo over most of, then it goes to some 7th chord that you can't figure out what to do over, try this trick. For example, cool song - Robben Ford's Prison of Love, it's mostly just blues in Gm, but instead of going to the iv (C), it goes to the #V - Eb9, then to C9, then to D9. So what do I play over the Eb9? I just go to the 6th fret and play Bb minor stuff. Same on any minor blues with a #V like Thrill is gone. It's also a good way to just mix it up. If you've been playing a lot of Rock & Blues stuff all night and are tired of your own pentatonic stuff, and here comes G7 again, just go to D minor and don't bend and you've thrown in a "jazzy" solo. Give it a try..... *I know, I know, the best thing is to really learn theory, harmony, diatonic stuff, modes, learn 100 jazz tunes from the real book, diminished stuff, don't learn modes, tritone subs, etc., etc., blah, blah. I'm just trying to throw out something that will give folks a little jump while they are also doimg all of the other stuff.
