The E♭ Dorian scale has 7 notes: E♭ – F – G♭ – A♭ – B♭ – C – D♭. Dorian is a minor scale with a bright major 6th. That one note lifts the sadness of the natural minor and gives a cool, soulful sound: the scale of funk vamps, Santana solos and modal jazz. In Indian music it is Kafi thaat.
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), ♭7 (D♭ instead of D).
The explorer above is set to E♭ Dorian: 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.
