In EarSketch, what does 'tempo' control?

Tempo refers to the speed at which music is played or performed, measured in beats per minute (BPM). In EarSketch, adjusting the tempo changes how quickly or slowly the musical beats are presented, which fundamentally affects the overall feel of the composition. A higher tempo results in a faster-paced piece, which can evoke excitement and energy, while a lower tempo can create a more relaxed or somber atmosphere.

Understanding tempo is essential when composing music because it sets the rhythmic foundation and influences how other musical elements, such as melody and harmony, interact with each other. The correct choice highlights the pivotal role of tempo in shaping the listener's experience and emotional response to the music being created.
