When a musician is instructed to play "subito", how should they adjust their performance?

The term "subito" is of Italian origin and translates to "suddenly" in English. In the context of music performance, when a musician sees "subito" in their score, it indicates that they should make an abrupt or immediate change in dynamics or articulation. This command is typically used to instruct musicians to either play loudly or softly in an unexpected manner, enhancing the emotional impact of the music.

Understanding this term is crucial for performers, as it highlights the interpretive elements of music that contribute to expressive playing. The sudden nature implied by "subito" creates contrast and can serve to surprise the listener or add drama to the piece.

Options such as "gradually," "softly," or "with stringency" do not convey the same immediacy associated with "subito," as they suggest a more measured or gentle approach rather than the prompt and dynamic change intended in the musical instruction. Therefore, the correct interpretation revolves around the element of surprise and immediacy found in the word "suddenly."
