The document emphasizes the artistic merit and functionality of the pedal harpsichord as a medium for vital music, highlighting its historical and practical significance.

They were given to Johann Christian Bach, the youngest son. Why did the frugal J.S. Bach have three such instruments?

Playing the organ in the days before wind could be supplied by mechanical power meant finding human energy and paying for it. (Apparently only painters were able to locate the charming winged cherubs abundantly found pumping organs in old paintings!) Moreover, churches were not heated in winter. So the pedal harpsichord started as a practice instrument.

A student of harpsichord style recognizes that some of the three stave music of Bach and his contemporaries is as closely related to the harpsichord as to the organ. The Passacaglia is marked “Cembalo e Pedale.” It will probably never be known with any certainty which works were intended for organ and which for pedal harpsichord, or whether all were used interchangeably. Regardless of historical evidence, the pedal harpsichord, as all other instruments, must stand on its own artistic merit as a medium for vital music.

The present pedal harpsichord has the following specification:
