Luigi Rodolfo Boccherini was an Italian classical era composer and cellist whose music retained a courtly and galante style while he matured somewhat apart from the major European musical centers. Boccherini is most widely known for one particular 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. Boccherini composed several guitar quintets including the "Fandango" which was influenced by Spanish music. His biographer Elisabeth Le Guin noted among Boccherini's musical qualities "an astonishing repetitiveness, an affection for extended passages with fascinating textures but virtually no melodic line, an obsession with soft dynamics, a unique ear for sonority, and an unusually rich palette of introverted and mournful affects."
