G Harmonic Minor scale on the guitar fretboard

The G Harmonic Minor scale is made of G (the root), A (major second), Bb (minor third), C (perfect fourth), D (perfect fifth), Eb (minor sixth) and F# (major seventh). The fretboard shows every one of them across the neck in standard tuning (E A D G B E), and plays them back so you can hear the scale.

The harmonic minor scale is the natural minor with a raised seventh, which leaves a gap of three semitones between the sixth and seventh degrees. That gap is easy to spot on the neck as a wider step. It sits between the natural minor and the melodic minor scale.
