Known by and large for his seemingly inexhaustible supply of lighthearted operas, Gioachino Rossini did not restrict himself to that genre alone. As a boy of only 12 years, he was already accepting commissions to write small chamber works, including the present set of six string sonatas commissioned by the wealthy Agostino Triossi. Triossi was an accomplished amateur double bassist, a fact to which Rossini paid homage by scoring the six sonatas for a quartet made up of two violins, cello, and bass.
