The Quasi-Chromatic Scale
What's a few missing notes between friends?
The quasi-chromatic scale is not really a scale - it's the 1-2-3-4 pattern on all strings, so it's the chromatic scale with some notes missing. The fretboard diagram shows all the notes that should be played in this exercise along with fingerings (each finger on each fret).
The whole point of this exercise (apart from warming up) is to synchronize your hands while gradually increasing the speed.
