A '''comma pump''' is a harmonic sequence (or chord progression) wherein the tuning base shifts up or down by one [[Comma|comma]]. This means that in [[Just_intonation|JI]], the chord prgression would not return to the original starting pitch, but a different pitch that is a comma off. If the chord progression is repeated many times, the tuning will steadily rise or fall (and also an unlimited number of different pitches would be required). | A '''comma pump''' is a harmonic sequence (or chord progression) wherein the tuning base shifts up or down by one [[Comma|comma]].
