Augmented 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 G

(perhaps shifted to begin with E or with G) and draw notes follow a repeating sequence of

E G B

though perhaps with a different initial sequence.

For example:

! hole ||  1 ||  2 ||  3 ||  4 ||  5 ||  6 ||  7 ||  8 ||  9 || 10 || 11 || 12 |- ! blow note || C || E || G || C || E || G || C || E || G || C || E || G |- ! draw note || E || G || B || E || G || B || E || G || B || E || G || B |}
