In EarSketch, how is a function defined?

In EarSketch, a function is defined as a reusable block of code. This means that a function is created to perform a specific task, and it can be called multiple times throughout a program without needing to rewrite the same code. This promotes efficiency and organization within the coding process, allowing programmers to compartmentalize their code and make it easier to read and manage. Functions can take inputs, known as arguments, and can produce outputs, facilitating complex operations with simpler, modular pieces of code.

For example, in the context of music production within EarSketch, a function could be designed to apply a specific audio effect or sequence of commands repeatedly without the need for duplication, thus streamlining the creation and editing process. The other choices do not align with the concept of a function in programming; a musical genre, audio effect, and arrangement of notes pertain to music composition and production rather than the coding structure used to implement those concepts.
