Although the fourth movement is very enjoyable and lively, as indicated by the marking "Allegro molto," it should be played at a very fast tempo. This means the triplets will also be quite fast, making it a movement that showcases technical prowess.

However, if the tempo is rushed even slightly, listeners may lose track of the beat, so caution is advised.

For instance, the sixteenth-note triplets appearing in measures 11-14 include a chord on the first beat in the left hand, which should largely prevent losing the beat. However, measures 15-18 lack chords and feature a continuous repetition of the exact same pattern, making it a section where it's easy to lose the beat. When you reach this section, try adding a slight accent to the note on the first beat (left hand). This should help in maintaining the beat.

Above all, keep in mind the goal of delighting the listener with technical skill and surprise, and play with a bright, clear touch, without fluctuating the tempo.
