D♭ Super Locrian (Altered Scale) in Practice

The D♭ Super Locrian (Altered Scale) uses the key signature of 5 flats (B♭, E♭, A♭, D♭, G♭). Db major has five flats and is enharmonically equivalent to C# major. It has a warm, veiled quality and appears in Romantic piano literature and jazz compositions. On guitar, D♭ positions offer comfortable transposing instrument keys for this scale.

The Super Locrian (or Altered scale) is mode VII of melodic minor. It contains every possible alteration of the dominant scale and is the definitive jazz scale for altered dominant chord resolution. When played starting on D♭, the 7 notes are D♭, D, E, F, G, A, B. In this key the signature has 5 flats (B♭, E♭, A♭, D♭, G♭). Db major uses all five black keys of the piano, placing the hand naturally on the raised keys and creating a legato, connected feel. Modern R&B and neo-soul producers often write in Db because keyboard players find the five-flat hand position physically comfortable for extended improvisations.
