Did Johann Sebastian Bach write for the harpsichord?

Answer 1

Yes many peices.

Without meaning to contradict the above, the actual number of Mr. Bach's harpsichord pieces is likely unknown since it isknown that much of his music did not survive the centuries. In any case he did, indeed, write music for the harpsichord, primarily between 1708 and 1717 during his tenure as organist and violinist, and eventually, concertmaster, at the court of Duke Wilhelm Ernst in Weimar, Germany.
