Together these collections constitute C.P.E. Bach's largest-scale publishing venture and the preparation and sales (it was a 'Selbstverlag' operation) occupied much of his energy for the final ten years of his life.
These collections have now appeared in two volumes (CPEB:CW Series I, vols 4.1 and 4.2) at the amazingly low price of $20 (£12.50) a volume (thanks to the support and subvention of the Packard Humanities Institute — would that more complete editions had such enlightened patronage).
In them you can find a mixture of Bach's most famous sonatas, rondos and fantasies suitable for both the clavichord and the forte-piano (and one alternative rondo movement included in the collection for the first time).
The aim of the edition as a whole is to have the complete works in print (some 109 volumes) by 2014, the 300th anniversary of Bach’s birth.
