It is in ternary form.

A [a (measures 1-4) + a1 (measures 5-8)]

B [b (measures 9-12) + b1 (measures 13-16)]

*Since the piece returns to A from measure 16 via a Da Capo and concludes at the Fine in measure 8, it is effectively in ABA ternary form.

The "State Fair" in the work's title refers to an event held in various U.S. states from late summer to early autumn. Reading the text written in the score reveals its nature: it seems to be a very fun and lively event, with marching bands parading.

The key is C major. In the opening two measures, a mobile figuration emerges in the left hand. The repeated-note motif in measure 2 is later developed in the B section. In measure 3, there is a movement where a single-note arpeggiated line is passed from the left hand to the right hand. Practice this section to ensure a smooth transfer between the left and right hands.

As mentioned, in the B section, the repeated-note motif from measure 2 (right hand) is developed. The repeated notes create a bouncy rhythmic feel, conveying the joy of the State Fair, a type of festival.
