Bennett was acknowledged both in England and Germany as an outstanding pianist, and his finest and most characteristic music was composed for his own instrument. As well as numerous works for solo piano, including two sonatas, he composed six piano concertos and a single-movement Caprice for piano and orchestra. He gave public performances of all his works for piano and orchestra with himself as soloist. It was during the heady days of Bennett's third long visit to his friends in Leipzig, from January to March 1842, that he mentioned in correspondence that he was working on a new concerto, which he hoped to perform before leaving for London. In the event, this did not happen, but a substantial amount of work must have been done at this stage on what was to become the unpublished Piano Concerto No. 6 in A minor, WO 48. Bennett did further work on the concerto in the summer of 1843 and hoped to publish it, but changes to his personal circumstances contributed towards further delays. His son claimed that he always intended it to be published, but as the years passed, the more out-of-date it became.
