Have always loved this quote from Bruce Lee:
All fixed set patterns are incapable of adaptability or pliability. The truth is outside of all fixed patterns.
The cool thing about playing 1 or 2 notes at a time: fingerings and positions don't really matter. When you get to 3 or more notes simultaneously, things get a little less flexible.
This also is very different than learning a written out piece of music or lick, where the fingerings & positions are there to help you play the passage or line easier. This is more about improvisation, and letting your hands figure out what makes sense for you (whereas the same fingering might not feel good or practical to another guitarist.)
Also, Bruce Lee is the coolest human being that has ever walked planet Earth.
Playing horizontally made more sense when I started thinking of these scale degrees as 'bass notes' of a future chord.
I don't know about you, but I find playing horizontally on the fretboard more enjoyable than playing vertically (feels like 6 pianos, as Gene Bertoncini would say!)
Also, I've been mostly leaving out open strings to keep the voicings simple and movable (except where the open string falls into the position of the voicing).
'C Major' scale degrees on the 6th String:
The numbers below the treble staff are the scale degrees (again, thinking of these as bass notes of a future chord)
The numbers on the tablature staff are the usual fret numbers.
Roots (C) are in GREEN
Initially, I wasn't playing Partimento ideas with any kind of rhythmic motive. But after the muscle memory kicked in, I've found it very helpful to choose one and stick to it for awhile (even on a simple scale like this, just to get into the habit)
To start with, I've been adopting a rhythmic motive from 'Happy Birthday' (without dotted rhythms to simplify):
Here are the horizontal scales on the 5th, 4th, and 3rd strings:
'C Major' scale degrees on the 5th String:
'C Major' scale degrees on the 4th String:
'C Major' scale degrees on the 3rd String:
And here are the horizontal scales on the 2nd and 1st strings:
The 2nd string can be a single note, or the root of a future diad
The 1st string is a single note (not the root of a future chord, for now)
At first, I hadn't included the 1st and 2nd strings, but as I'm going back through the material -- I think it'll be useful for later on
'C Major' scale degrees on the 2nd String:
'C Major' scale degrees on the 1st String:
