Much of Boccherini's
chamber music follows models established by
Joseph Haydn; however, Boccherini is often credited with improving Haydn's model of the string quartet by bringing the cello to prominence, whereas Haydn had frequently relegated it to an accompaniment role. Some sources for Boccherini's style are in the works of a famous Italian cellist,
Giovanni Battista Cirri, who was born before Boccherini and before Haydn. A virtuoso cellist, Boccherini often played violin repertoire on the cello, at
pitch, a skill he developed by substituting for ailing violinists while touring. This supreme command of the instrument brought him much praise from his contemporaries (notably
Pierre Baillot,
Pierre Rode, and
Bernhard Romberg), and is evident in the cello parts of his compositions (particularly in the quintets for two cellos, treated often as cello concertos with
string quartet accompaniment). He wrote a large amount of chamber music, including over one hundred string quintets for two violins, viola and two cellos (a type which he pioneered, in contrast with the then common scoring for two violins, two violas and one cello), a dozen guitar quintets, not all of which have survived, nearly a hundred string quartets, and a number of
string trios and
sonatas (including at least 19 for the cello). His orchestral music includes around 30
symphonies and 12 virtuoso
cello concertos. Boccherini's works have been catalogued by the French
musicologist Yves Gérard (1932–2020) in the
Gérard catalog, published in London (1969), hence the "G" numbers applied to his output. Boccherini's style is characterized by
Rococo charm, lightness, and optimism, and exhibits much melodic and rhythmic invention, coupled with frequent influences from the guitar tradition of his adopted country, Spain. ==Recordings==
