Diminished tuning is a system of choosing the reeds for a diatonic wind instrument (such as a harmonica or accordion) in which the blow notes repeat a sequence of
- C E♭ F♯ A
and draw notes follow a repeating sequence of
- D F G♯ B
(perhaps shifted to begin with E♭ and F, with F♯ and G♯, or with A and B).
For example:
