K 450 Piano Concerto No 15 in Bb,

The Piano Concerto No. 15 in B-flat major, KV. 450 is a concertante work for piano and orchestra by Wolfgang Amadeus Mozart. Mozart composed the concerto for performance at a series of concerts at the Vienna venues of the Trattnerhof and the Burgtheater in the first quarter of 1784, where he was himself the soloist in March 1784. The concerto is quite difficult from its many quick scale patterns which must be played perfectly and also from its many fast chord patterns moving up and down. Beginning with this concerto, Mozart began to use the term "grand" to describe his concerti such as K.450 which feature a prominent and required wind section for the ensemble. WIKIPEDIA
