What is the meaning of "crescendo" in music?

The term "crescendo" in music refers specifically to a gradual increase in volume or intensity of sound. It is a dynamic marking indicating to the performer to start softly and progressively play louder. This technique is commonly used to build emotional intensity or to create a sense of excitement within a piece.

Understanding the context of music dynamics is vital; while other choices relate to qualities of sound, they do not define what a crescendo is. For instance, one might confuse it with decrescendo, which indicates a decrease in volume, or assume that it refers to a sudden change in dynamics, which describes more abrupt shifts rather than a gradual build-up. Additionally, a steady tempo pertains to maintaining a consistent speed rather than volume, further distinguishing it from the concept of crescendo.
