Which word means "suddenly" in Italian musical terminology?

In Italian musical terminology, the word that means "suddenly" is "subito." This term is often used in music instructions to indicate that a particular change should occur abruptly or without gradual transition. For instance, "piano subito" instructs musicians to suddenly play softly, while "forte subito" means to suddenly play loudly.

The other options, while related to different aspects of music, do not convey the meaning of "suddenly." "Presto" refers to a fast tempo, "piano" means soft, and "andante" describes a moderate speed, typically a walking pace. Each of these terms addresses different musical characteristics and do not share the connotation of abruptness found in "subito."
