Ridolfo Luigi Boccherini was an Italian composer and cellist of the Classical era whose music retained a courtly and galante style even while he matured somewhat apart from the major European musical centers. He is best known for a minuet from his String Quintet in E, Op. 11, No. 5, and the Cello Concerto in B flat major. The latter work was long known in the heavily altered version by German cellist and prolific arranger Friedrich Grützmacher, but has recently been restored to its original version.

The cello ( CHEL-oh), or violoncello ( VY-ə-lən-CHEL-oh, Italian pronunciation: [vjolonˈtʃɛllo]), is a bowed (sometimes plucked and occasionally hit) string instrument of the violin family. Its four strings are usually tuned in perfect fifths: from low to high, C2, G2, D3 and A3. The viola's four strings are each an octave higher. Music for the cello is generally written in the bass clef, with tenor clef, and treble clef used for higher-range passages.
