He was 12 years old at the time and was living in the home of the amateur double bass enthusiast Agostini Triossi.

[2]With the exception of a single song, the six string sonatas are considered Rossini's earliest compositions.

Though the music presents weaknesses and deficiencies, the sonatas are still considered remarkable works for a composer of such young age and inexperience.

In 1942, the sonatas published by Ricordi were rediscovered, and in 1954, Rossini's original score was found in the Library of Congress in Washington, D.C.[1] Rossini's six string sonatas are scored for four string instruments: two violins, a cello, and a double bass.

[1] The sonatas exhibit multiple departures from musical expectations: the material is not formally developed in ways characteristic of other classical works, and the typical role of the cello is magnified with the introduction of a double bass.
