Among the ideal music for the uninhabited island are the six suites for solo cello by Bach. The great Rostropovich wrote about this music: 'Nothing in this world is more dear to me than these suites, in which you always discover something new'. Half a century later it was mainly Boccherini who enriched the cello repertoire. Beethoven did not write many cello sonatas, but they are nevertheless a beautiful reflection of his much-discussed 'three periods'. Thus the powerful Third Sonata was written in the same period as Beethoven's Fifth Symphony. Romantic cello literature also excels more in quality than in quantity (Chopin, Schubert, Schumann, Brahms, Franck, Rachmaninov). In his monumental Quintet for strings (not formally part of this section) Schubert did not double the viola, but the cello.
