his pieces have been included either in the _Trésor des Pianistes_,
the _Maîtres du Clavecin_, or Pauer's Collections of old music.

This chapter is headed: "A Contemporary of Kuhnau." The latter

But at that time Pasquini was over sixty years of age; it is therefore

master as a writer of clavier sonatas.

studied composition and clavier-playing with his father. His brother,
Wilhelm Friedemann, his senior by four years, went through a similar
course, but learnt, in addition, the violin under J.G. Graun.
