What does "Subito" instruct a musician to do?

The term "Subito" is an Italian musical instruction that translates to "suddenly." When a composer uses this term in a piece of music, it suggests that the performer should make a sudden change in dynamics or style. For instance, a musician might be instructed to play suddenly louder or softer, or to change an articulation abruptly. This creates an expressive effect that can enhance the emotional quality of the music.

Other possible choices, while relevant to music terminology, do not encapsulate the specific meaning of "Subito." For example, sustaining the note, playing regularly, or slowing down involve different directives that do not convey the immediacy and suddenness implied by "Subito."
