Another form of coupler found on some large organs is the divided pedal. This is a device that allows the sounds played on the pedals to be split, so the lower octave (principally that of the left foot) plays stops from the pedal division while the upper half (played by the right foot), plays stops from one of the manual divisions.
The first use of pedals on a pipe organ grew out of the need to hold bass drone notes, to support the polyphonic musical styles that predominated in the Renaissance.
