Despite being in C major, this first movement is lively, joyful, and cheerful.

In this first movement, the thematic tutti sections appear a total of six times:

• Measure 1: C major, G major, long version
• Measure 16: C major, short version
• Measure 31: A minor, C major, long version
• Measure 71: C major, short version
• Measure 88: G major, V7, C major, short version

First, let us examine the section from the first theme to the second. The solo begins at measure 8, and from measures 8 to 12, quarter notes or eighth notes are observed on the first beat. However, from measure 13 onwards, sixteenth notes are densely packed in either the left or right hand, eliminating the sense of settling on the first beat as before. Thirty-second notes also appear (from measure 13), leading to the second tutti at measure 16.

After the second tutti, quarter notes reappear in measures 20 and 21, but only until measure 24. From measure 25 onwards, the music is again filled with sixteenth notes, increasing the tension and leading to the third tutti.

Thus, it can be observed that after each tutti, there is always a 'calm,' but the music gradually builds in tension, reaching a peak just before the next tutti. Similarly, dynamics should be applied with direction, generally reaching the next tutti with a crescendo.
