MUSIClassical notes: Mozart, Piano Concerto No 2 in Bb K 39

Wolfgang Amadeus Mozart began his series of preserved piano concertos with four that he wrote at the age of 11, in Salzburg: K. 37 and 39-41. The autographs, all held by the Jagiellonian Library, Kraków, are dated by his father as having been completed in April (K. 37) and July (K. 39-41) of 1767. Although these works were long considered to be original, they are now known to be orchestrations of sonatas by various German virtuosi. The works on which the concertos are based were largely published in Paris, and presumably Mozart and his family became acquainted with them or their composers during their visit to Paris in 1763–64. By using movements from the sonatas of other composers, the young Mozart seems to have begun to learn how to cope with the structural problems of composing in the piano concerto form. No. 2 (K. 39) in B flat major The concerto is scored for strings, piano (or harpsichord), and pairs of oboes and horns, as above. The movements are: Allegro spiritoso Andante staccato Molto allegro The first and third movements are again from Raupach (Op. 1, No. 1), whilst the slow movement is based on the opening movement of Johann Schobert's Op. 17, No. 2, a composer admired by Mozart
