Which term refers to a slow tempo in music?

The term that refers to a slow tempo in music is "lento." In musical terminology, "lento" specifically indicates a slow and leisurely pace, typically suggesting a tempo in the range of about 40 to 60 beats per minute. This term helps performers understand how to approach the piece regarding speed and expression, creating a sense of calm or contemplation.

"Maestoso," while also indicating a certain majesty or grandeur, does not specifically denote a slow tempo as its primary meaning. "Piano" refers to dynamics or volume, indicating softness in sound rather than tempo. "Allegro," conversely, signifies a fast and lively tempo, often ranging from about 120 to 168 beats per minute. Understanding these distinctions helps musicians interpret and perform music more accurately according to the composer's intentions.
