There's more...

In this recipe, we used three musical notes to demonstrate the process of defining notes and then playing each note back. Of course, there are many more notes that can be defined.

A good learning exercise is to find the frequency of other popular notes and go through the process of defining them and playing them. Even though three notes seems like too few, they are enough to play a recognizable melody. We will see in the following recipe how these same three notes can be combined to play a popular melody.
