The first movement fully expresses Haydn's joy and humor.

Although it is fundamentally an instrumental ensemble, it can be considered to have two types of scoring: a "small instrumentation" and a "large instrumentation." The distinction can be made based on the left-hand notes: sections with left-hand octaves represent the large instrumentation, played with greater volume, while sections with single left-hand notes represent the small instrumentation, played with less volume.

For example, from measure 1 to the first beat of measure 2, it is a large instrumentation. From the upbeat of the first beat, a solo instrument begins playing FFF, and this instrumentation continues until the downbeat of the second beat of measure 7.

The large and small instrumentations are not necessarily separated by sections; for instance, measure 16, beat 1, might be a large instrumentation, followed suddenly by a small instrumentation from beat 2.

Furthermore, there is an aspect of Haydn's characteristic "surprise," such as the sudden shift to a large instrumentation at measure 18, beat 1. Passages with 64th notes, such as measures 8-9 and 35-36, evoke Haydn's characteristic jocular image, as if being rattled off rapidly. Above all, play it with enjoyment.
