What does the term "ritenuto" indicate in music performance?

The term "ritenuto" is a musical directive that instructs performers to hold back or slow down the tempo. It conveys a sense of sudden restraint, often used to create a dramatic effect or to emphasize a particular phrase within the music. When musicians see "ritenuto" in a score, they know to temporarily reduce their speed, which can enhance the emotional impact of the piece being performed.

In contrast, the other choices suggest different types of musical expression. Playing faster or increasing volume would contradict the intention of "ritenuto," as they both imply a more vigorous or intense approach rather than a restrained one. Similarly, playing more expressively typically involves nuanced dynamics and phrasing but does not equate to the specific slowing down that "ritenuto" denotes. Thus, recognizing "ritenuto" as a direction to hold back is crucial for accurately interpreting and performing the music as intended.
