Use buttons to ‘tune in’ the pitch of a variable note or hold them down to create fun sound effects.

New Concept: Changing variable values
So far, you’ve used variables as ‘names for numbers’ that made your code easier to change and update by programmers. In this project, you instead use a variable as a number that can be changed by the code and doesn’t have a constant value as the code runs. This is another important feature of variables - you can update them as the code runs.
It’s almost impossible to keep track of the value of the pitch variable in this code because it can change so quickly, but try to imagine what value ‘pitch’ has as you play with this project. If you can visualize the value of a variable that you’re using, it’s much easier to find and solve problems that can come up when you’re using them in place of number values.
