The tempo marking is Vivo, which means "to live" in Portuguese and "lively" in Italian, so it can be understood as Vivace. Vivace means lively, and it does not necessarily mean "fast." However, considering the rhythmic accompaniment in 2/4 time, the approximate tempo is not difficult to imagine. Although this piece is from the Romantic period, it is advisable not to apply any rubato. As evidence, tempo-related indications are only written between measures 19 and 21. Therefore, the other sections should proceed at a consistent tempo, almost like a metronome. Let's discuss dynamics. This piece is characterized by sudden changes in dynamics. In short, subito f and subito p are characteristic features that must be expressed very clearly. For example, a forte is written in measure 29 and a piano in measure 31, but the approach should not be to diminuendo from measure 29 to 30 to reach piano. Instead, measures 29-30 should remain forte throughout. Then, suddenly change to piano in measure 31. Maintain piano until forte returns in measure 33, where it becomes subito f. The same applies to all subsequent instances. Regarding the musical aspect, this piece is a very comedic and optimistic work. Try to perform it with the image of various characters appearing. For instance, it can be said that the melodic line is in the right hand from measures 29 to 36. From measure 37, this shifts to the left hand. You might consider measures 29-36 as a female character and measures 37-44 as a male character, for example.
