What can be deduced about variables' flexibility?

Variables are fundamental concepts in programming that allow you to store and manipulate data. They are designed to be flexible, meaning they can hold different types of values over time. For example, you can assign a variable to hold a number initially, and later change it to hold a string or another type of data. This dynamic nature is critical for creating adaptable code, as it enables programmers to modify the content based on varying conditions or requirements within a program.

In the context of EarSketch, where music is composed by manipulating various elements, the flexibility of variables allows composers to adjust values related to tempo, pitch, and other musical parameters as needed. This capability to change what variables store is essential for creating dynamic, interactive compositions that respond to user inputs or changes in the musical structure.
