There's more...

This recipe is written in a generic fashion: you take a popular melody, provide the sequence of notes and each note's associated frequency, and then add the melody to your project. The melody in this recipe has each note play for the same duration.

However, there are many melodies that might mix quarter notes and eighth notes. These melodies will require a different duration of time to be defined for each note. The recipe could be expanded so that we could keep track of each note to play and the duration that each note would need to play for.
