Mixtures

When a four-rank mixture is drawn and a key played, four pipes sound. A mixture usually supplies HIGH PITCHES that are used in combination with lower-pitched stops that must be drawn independent of the mixture.

FOR EXAMPLE:

The Plein Jeu IV on the stop list to the right would not usually be drawn without the support of the Bourdon 8', the Prestant 4', and the Blockflöte 2'.
