As with one octave scales, certain keys are used below as examples but practice the patterns in various keys by playing the same pattern/fingering at different starting frets. I’ve started each scale around the 4th and 5th position for left hand ease. I’ve chosen these patterns because they utilize a variety of shifts, fingering concepts, guide fingers, or squeeze shifts. A squeeze shift is a one fret micro shift often including a fingering just before that will allow sustain of the previous note.
