The stops had multiplied and the organist _called_ them by means of registers which he drew out or pushed back at will.

In order to give greater resources, the builder multiplied the keyboards.
Pedals were introduced to help out the keyboards.

At that time Germany alone had pedals worthy of the name and worth while in playing an interesting bass part.

In France and elsewhere the rudimentary pedals were only used for certain fundamental notes or in prolonged _tenutos_.
No one outside of Germany could play Sebastian Bach's compositions.
Playing on the old instruments was fatiguing and uncomfortable.

The touch was heavy and, when one used both the pedals and the keyboards, a real display of strength was necessary.
