„There will hardly be any other piece that might fit the term „air“ (song, melody) – derived from the French language – better than the composition on hand. To facilitate its performance in various instrumentations, all the voices are written in C (flute, violin, ...) and Bb (clarinet).
Additionally, the third voice is written in Eb (alto clarinet, alto saxophone) and F (basset horn).
This way, many different settings are possible.“
