Wolfgang Amadeus Mozart : Viennese Sonatina No. 1, K. 439b – 1st movement, Allegro Arr. de Michael Schopen

The six Viennese Sonatinas are not original compositions by Mozart for the piano. Rather, they are contemporary arrangements of his wind divertimenti KV 439b for three basset horns. The organ arrangement is not based on the piano score, but follows the wind parts, especially in terms of phrasing. Occasionally, the movement has been filled out somewhat, and the slow movement has been transposed – as in the piano arrangement – to create some tonal variety when the sonatina is performed in its entirety.
