This is a very bright and enjoyable first movement. Although the tempo is marked Allegro, a more moderate, calmer tempo, closer to Moderato, offers the advantage of making trills and turns easier to play, while simultaneously allowing for the effortless performance and comfortable listening of intricate notes such as sextuplets, triplets, and thirty-second notes.

Naturally, the tempo should be consistent throughout, so be careful not to let it change from one section to another. Pay particular attention to sections without a clear rhythmic accompaniment, such as measures 23-28, where the tempo tends to accelerate. Maintain a consistently unwavering tempo, as close to a metronomic pace as possible. This will enable the listener to accurately perceive the beat.

The peak point begins from measure 23, with the tension reaching its highest around measure 31.

There are also editions with differing articulations and rhythms. As articulation is generally felt to be flexible, please apply legato and staccato based on the performer's discretion. There is no single "correct" or "incorrect" approach.
