Ignoring octaves, every note in a on the guitar shows up in many different places. I'd like to practice all the achievable three note chords on the guitar so that I can move my chord progressions up and down and across the neck better.
By "three note chords", I mean major, minor, dominant and aug/dim together with any color notes (7, 9, 11, 13). The root can be implied and the chords can be in any voicing.
I'm interested in the three note chords because they give the richest tone while still playable at two chords per bar at 120bpm, which is where I usually live.
Three note chords also give me the ability to comprehend at performance tempo what I'm doing and where I can go. If I play grips of more than three notes then I'm just playing grips and sequences of grips, which doesn't always work for the kind of improvisation I do with my band.
What I currently do is try to construct new voicings during practice time and then play the voicings as harmonized scales at one or more positions. But I need a systematic way to string the chord voicings and substitutions at a single position and all the possible positions along the guitar neck.
Are there any Spaced Repetition Systems or other automated tools out there that I could use for drilling on all the three note chords possible for particular chord progressions such as I-IV-V, ii-V, ii-I, etc.?
I'm already familiar with the Freddy Green system but I'd like to work on new grips.
