What is the meaning of "accelerando" in musical terminology?

"Accelerando" is a term used in music to indicate that the tempo should gradually increase, meaning the performer should play faster over a specified passage. This directive enhances the energy and momentum of a piece, often building excitement or reaching a climactic moment in the music. As musicians interpret the term, they will typically make sure to achieve a smooth and controlled increase in speed, contributing to the overall expressive quality of the performance. The other terms do not fit this definition: "gradually slower" refers to the term "ritardando," "remain steady" suggests no change in tempo, and "play softly" translates to "piano," indicating dynamics rather than speed.
