Selected Duets for Flute, Page 13 Number 3, performed by David Summer.

The duet is entitled "Jigg". It's a spelling variation on the word "Jig". A "Jig" is an Irish dance form and the tunes for these are generally in a fast 6/8. They are played in a light manner.

When 6/8 is at a fast tempo, it's often said to be "in 2". That is, where you are heavily accenting 2 beats to a measure, the first and the fourth beats.

The metronome setting for this performance is dotted quarter note = 72.
