Johann Nepomuk Hummel (1778 - 1837) is worth playing just for his wonderful name! He wrote 3 sonatas for flute and piano, the best of which I think is the one in D major Op 50. This is a longer and more substantial work, with an increased range of notes for the flute and change in the role for the piano to equal partner. Although still in the three movement fast, slow, fast form, the first movement is marked Allegro con brio and you will need strong articulation as well as a good technique to convey it's power. Unusually, the Andante is in the tonic minor, beautifully unsettled and dark, and it leads straight into the closing Rondo Pastorale. Sunny in outlook but anything but straightforward to play, the writing is peppered with more complex rhythms and sudden accents in both parts, and the virtuosity of the writing means that the pair of you will bring the house down at the end!
