Mozart perfected the form of the modern piano concerto, which from about 1750 begins to show its affinity with sonata form, in his 21 concertos for solo piano and orchestra. The D minor piano concerto K.466 is one of the fewconcertos which remained in concert repertoire in the years following Mozart’s death. After the resuscitation of the other concertos it remained the most popular of all Mozart’s works in this genre, and there can scarcely be apianist who has not studied it or played it in a concert.
