Concerto for Piano № 1 in F Major, KV 37 - Salzburg, 1767This concerto is scored for strings, piano (or harpsichord) and pairs of oboes and horns. The three movements are:1. Allegro2. Andante - in C major3. AllegroThe first movement is based on a sonata movement by Hermann Friedrich Raupach for keyboard with violin accompaniment, from a set of six published in Paris in 1756. The provenance of the second movement is unknown, although Eric Blom, the editor of the 5th edition of Grove's Dictionary (1954), suggested that it was in fact by Mozart. The final movement is based on a sonata by the Strasbourg based Leontzi Honauer. By comparison to Mozart's later concertos or even to those of J. C. Bach, these are slight works. The preludes that Mozart added to the sonatas do not contain a wealth of themes, as is typical for his later efforts, nor does the exposition or middle section add new thematic material. The role of the keyboard as soloist or continuo is not always clearly delineated. Nevertheless, some traces of his later structures can be detected: for example, the relative sizes of the sections is approximately similar, albeit on a smaller scale.
