Mixture stop

Mixture stop (Fr.: jeu composé; Ger.: Mixtur, gemischte Stimme), compound organ stop having more than one pipe to a key, the fundamental plus one or more of its harmonics, controlled by one drawstop. The tonal position of a mixture stop is indicated by the length in feet of the biggest pipe on the C0 key. In describing a mixture it is usual to indicate the number of ranks (133).
