What was the role of the pedal clavichord in music history? Was it a cheap practice instrument for organists or was it a teaching tool that helped contribute to the quality of organ playing in its golden age? This book documents an experiment in which an 18th-century pedal clavichord from Leipzig was duplicated (by Speerstra, an American musician, instrument builder, and doctoral graduate of the University of Göteborg) and used by students and teachers to generate information about the historical tradition. The instrument served as a focal point for a new exploration of J. S. Bach’s keyboard technique as preserved by his first biographer, J. N. Forkel (1802). 280 pages, 10 illustrations.
