E Whole-Half Diminished Scale notes: E F# G A Bb C C# D#. Formula: 1 2 b3 4 b5 b6 6 7. Chords that fit it: Edim, Edim7.
The whole-half diminished scale alternates whole and half steps: 1 2 b3 4 b5 b6 6 7. It is the natural choice over diminished 7 chords and shows up in jazz, film scores and fast metal runs. Like every diminished scale it repeats every three frets, so there are only three different ones.
