Selected Duets for Flute, Page 50 Number 4, Air, performed by David Summer.

This "Air", by GF Handel is a good duet to use when studying the "eighth-quarter-eighth" rhythm pattern. When the student can confidently alternate between this pattern and four eight notes, they likely have a good grasp of this syncopation.

Both sections of the duet start with staccato markings. The editor really should have added some marking to indicate that the staccato articulation should continue, as I've assumed in this performance.

The metronome setting for this performance is quarter note = 100.
