Melodies

Music is made of melodies. The Micro:bit library is designed with a rich collection of pre-loaded melodies. We can play a simple melody on the Micro:bit using the music module. The module contains 21 melodies. Some of the most popular ones are as follows:

music.DADADADUM
music.PRELUDE
music.RINGTONE
music.BIRTHDAY
music.WEDDING
music.BADDY
music.POWER_UP
music.POWER_DOWN

We can access the complete list using the dir(music) command. Connect your Micro:bit to your PC and run the following simple MicroPython code to play any of these melodies:

import music
music.play(music.BLUES)

We can play multiple melodies by pressing different buttons on the Micro:bit. In the following code, we are playing two different melodies by pressing buttons A and B on the Micro:bit. The following code will play the FUNK melody when button A is pressed and the DADADADUM melody when button B is pressed:

import music
from microbit import *
