F Double Harmonic Scale notes: F Gb A Bb C Db E. Formula: 1 b2 3 4 5 b6 7. Chords in this scale: F, Gb, Am, Bbm, Dbaug.
Double harmonic major has two wide steps, one on each half: 1 b2 3 4 5 b6 7. It is the classic Arabic and Byzantine sound, and the scale behind surf rock tunes like Misirlou. Over a major chord it sounds instantly exotic; play the b2 and b6 slowly and let them resolve.
