Bach, who was regarded as one of the most skilful harpsichordists of his time, left many
compositions for that instrument. From the pieces of his youth to the great collections of
his maturity (Partitas, French Overture, Goldberg Variations), not forgetting the Suites,
the two books of the Well-Tempered Clavier, and finally the preludes, toccata, concertos,
fantasias and fugues, the composer explored every musical genre that was performed at
that time on the instrument.
According to his biographer Forkel, Bach “regarded his musical parts as so many persons
engaged in conversation”. For the best possible rendering of the dialogue between the viol
and the harpsichord, we have chosen to use two typically German instruments, possessing
both clarity of articulation and a warm timbre.
