Db Dorian Mode in Practice
The Db Dorian Mode uses the key signature of 5 flats (Bb, Eb, Ab, Db, Gb). 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, Db positions offer comfortable transposing instrument keys for this scale.
The Dorian mode is a minor scale with a raised 6th degree, giving it a slightly brighter quality than natural minor. It is the characteristic sound of jazz and Celtic music.
