What is a 'track' in EarSketch?

In EarSketch, a 'track' refers to a layer for arranging sounds and samples. Each track can hold different audio elements, allowing users to organize their music in a structured way. By stacking multiple tracks, users can create complex compositions and mix various sounds together. This layering is fundamental to music production, as it enables the creation of harmony, rhythm, and texture within the piece.

The other choices do not capture the specific function of a 'track' in the context of music creation. A type of music genre describes a category of music rather than a structural component. A method for recording vocals pertains more to the process of capturing sound rather than organizing it. Lastly, a tool for editing audio effects relates to manipulating sound but does not describe the foundational aspect of how sounds are organized within a music project.
