G Melodic Minor (Ascending) scale on the guitar fretboard
The G Melodic Minor (Ascending) scale is made of G (the root), A (major second), Bb (minor third), C (perfect fourth), D (perfect fifth), E (major 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 ascending melodic minor scale is a minor scale with a raised sixth and seventh, so only the third marks it as minor. On the neck it looks like a major scale with one note lowered. Its descending form returns to the natural minor.
