[Flute/Guitar]
This is an arrangement of Etude in A by Fernando Sor for flute and guitar. The solo voice from this study is so clear that it fits perfectly on a melody instrument like the flute. The guitarist can concentrate on the accompaniment which becomes less difficult than the original etude.
In the time of my flute-guitar duo, I arranged quite some solo guitar music to a flute-guitar duo. In this way you could share the burden a bit and you had some quick music to play. The keys were less optimal for the flute (the flutes like flat keys better) but it played well enough.
