The E♭ harmonic minor scale has 7 notes: E♭ – F – G♭ – A♭ – B♭ – C♭ – D. The harmonic minor is the natural minor with its 7th raised a half step. The gap of three frets between the ♭6 and the 7 gives it its exotic, classical sound, and the raised 7th makes the V chord major, so it pulls strongly back home.
E♭ and D♯ are the same pitch, so this page covers both names; the notes are spelled from E♭, the way the key is usually written. Compared with the E♭ major scale it has ♭3 (G♭ instead of G), ♭6 (C♭ instead of C).
The explorer above is set to E♭ harmonic minor: the whole neck is mapped, and you can zoom into any of its 7 positions, change the labels to degrees or fingers, and hear it up, down and in patterns.
