F Diminished (WH) Scale
F Diminished (WH) contains 8 notes: F, G, G♯, A♯, B, C♯, D, E. It has 3 sharps: G♯, A♯, C♯. The step pattern is W–H–W–H–W–H–W–H.
The whole-half diminished scale reverses the half-whole pattern. It is the natural choice for melodic lines directly on diminished 7th chords.
The formula is 1, 2, b3, 4, b5, b6, 6, 7. While the HW version targets dominant chords, the WH version is used directly on diminished 7th chords, providing every chord tone plus four passing tones. The two diminished scales are complementary — what is a chord tone in one is a passing tone in the other. Together they cover all 12 notes.
Same symmetry advantage as the HW version: every pattern repeats at minor 3rd intervals (3 frets). Practice arpeggiating the underlying dim7 chord and weaving in the four passing tones to create smooth, connected lines.
