Learn To Play All Harmonic Minor Keys With Seven Scale Patterns.
The Harmonic Minor scale is a seven note scale with the eighth note completing an octave. Played on three notes per string, this scale can be played entirely with seven patterns. Each pattern can be played in any position on the fretboard. And because the root tone remains the same wherever the pattern is played, you can easily identify which key you’re in.
(Example) If you look at the chart, take pattern 1 and move it up the fretboard a half step, you land in the key of A# Harmonic Minor. Patterns are always played in order 1-7 starting over with pattern 1 after pattern 7, regardless of starting position all the way through till you run out of frets.
This scale is the only minor scale with 1 1/2 steps between the 6th and 7th degree, giving this scale a unique feel and sound. And is probably the most difficult to learn and master.
