The expository function is established immediantely through parallel phrases and repetition. The rhythm is four sixteenths, low density, and solfege is sol-mi-fa-re-do on each sixteenth. The flute line is accompanied by a violin line that makes the staccato even more emphasized. One of the things that shapes the phrases is the lack of staccato, there is especially emphasis on the contrast between the note lengths because of the low density. The flute line is repeated by strings and oboe. The orchestra then enters a developmental function. An aggressive line in the low strings creates a transistional function back into the expository one. The function is a little different, the sixteenth rhythm and solfege, stay the same, but it is more legato, with very little staccato. The flute then starts a sixteenth passage that slowly climbs up by steps. It then enters another sixteenth passage that doesn't go anywhere, just floats around in a low density, higher register. The same signal of the aggressive bass line in the strings is used to signal another transistional function to the first cadenza. After the cadenza, it repeats back to the beginning, and cycles into a new section briefly in a minor key. The expository funciton is stated again, I think it has been stated in the rondo about five times. The structure is the five part rondo. The entire piece maintains a liteness to it maintianed through very strict rhythmic and harmonic activity. The entire piece moves fast and aggressive, but because of its contrast to the lite sound of the flute, it maintains this flighty feel.
