Play sounds with music blocks. Play sounds with music blocks.
Have you ever tried to play a song on an instrument? Let's try coding the song "Happy Birthday" on the micro:bit ! Have you ever tried to play a song on an instrument? Let's try coding the song "Happy Birthday" on the micro:bit !
Let's start by adding the code in the music drawer that includes a single musical chord (or pitched sound) with the `play` block. Then insert the chord "C". Once you are done coding, don't forget to run your code in the simulator or the micro:bit.
