Songs can be divided into a rhythm, the constant beat the music follows. Shown in the diagram to the right, we have the note durations. One whole note (semibreve) lasts for 4 beats. Next, minums last for 2, and crotchets last for 1. We’ll only use semibreves, minums, and crotchets for basic songs.

Below is an example of ‘Mary Had a Little Lamb’ in sheet music. The letters have already been written below the notes. This is the example we will use for the guide, but feel free to find your own songs or even write your own music!

Now we need to start setting up the framework in our code to make music. We’ll begin by setting constants for each of the note lengths. A constant is a value used repeatedly throughout the code that never changes, which is perfect for what we need here. As all the notes are multiples of the Crotchet, we can use the diagram above and some simple multiplication to set all the constants. We also need to decide on an octave to use, so make a comment to remember this. For this example, we’ll use octave 4.

This part can take a little while, but we will use the ‘Play Note’ and the ‘Delay’ blocks to play each note individually. The ‘Play Note’ block starts playing the note on the Rover, and the ‘Delay’ block controls how long the note is played. We use the constants we made before to control how long we delay. Do this for each note in the song with the correct note lengths.
