I recently recorded some stuff on my guitar synth and was asked to explain what I was doing:
I use a number of techniques that involve
dodecaphonics (Sheets of Sound for Guitar)
parallel intervallic displacement
sequential forward motion
Synthentic pentatonic scales (7b9, min6, Maj7#5, 7sus4)
I'll discuss these in this thread or a series of threads. For # 5:
The technique I am currently working on expanding in my own playing is a variation of side-stepping combined with sequential forward motion. Hal Galper has a video and book out about forward motion but it basically revolves around taking groupings of 4 notes but starting them on the end of the previous beat instead of right on the beat. So the 2nd note of the pattern falls on the downbeat. I have been working on taking pentatonics or triads in forward motion and applying various side stepping techniques to them.
For example, over G7
Pentatonics: | Dmin pentatonic | Ebmin Penatonic | F#min Pentatonic | Dbmin Pentatonic |
Triads: | F | Gb | A Triad | E Triad |
i could play 8 notes of each or 4 notes of each depending on the harmonic rhythm.
I also do a variation of the forward motion where I play groupings of 5, 6 or 7 note groupings with the pentatonics and/or triads.
I have recently been trying to get more of the synthetic pentatonic scales under my fingers and I will augment the above example using the synthetic pentatonics.
