F Melodic Minor (Ascending) scale on the guitar fretboard
The F Melodic Minor (Ascending) scale is made of F (the root), G (major second), Ab (minor third), Bb (perfect fourth), C (perfect fifth), D (major sixth) and E (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.
