The Sonata in C Major is originally a flute solo transcribed for flute choir. It's written in four movements with the solo part moving to different voices. The piece calls for 3 C flutes with flute 2 switching one player to piccolo on occasion and flute 3 having an alternate Eb part which will facilitate some of the higher passages. The first movement , Andante Allegro, starts out with the solo in flute 1 until the Allegro section when it switches over to piccolo in flute 2. The second movement, Menuetto, has the solo in flute 3 or Eb. The Adagio movement returns the solo to flute 1 and the final Allegro goes back to the solo on the piccolo.
3 C flutes (one w/picc. & one w/opt.Eb fl.) , alto & bass flute.
