Sound - Music

2.9. Sound - Music#

2.9.1. Playing Music#

Use music.play to play a melody

music.play(music, wait=True, loop=False)

where

  • music is a list of notes (see “Custom Melodies” below)

  • wait determines whether the function will block execution of code until the music is finished

  • loop determines whether to repeat the playback

2.9.2. Tempo#

You can set the tempo of music playback by using

music.set_tempo(ticks=4, bpm=120)

where:

  • ticks is the number of sub-divisions per beat, to give finer control over duration of notes

  • bpm is the number of beats per minute

2.9.3. Stopping and Resetting#

You can stop the music with

music.stop()

or reset the music playback to default settings with:

music.reset()

2.9.4. Built in Music#

The music library contains example melodies that can be played for example:

  • music.NYAN

  • music.DADADADUM

  • music.BIRTHDAY

You can find the full list here https://microbit-micropython.readthedocs.io/en/v2-docs/music.html#built-in-melodies

Example#

from microbit import *
import music

music.play(music.NYAN)

2.9.5. Custom Melodies#

A custom melody can be created with a list of notes, which are defined using strings of the form:

NOTE[octave][:duration]

for example

C4:2

refers to middle “C”. It is the C in the 4th octave, played for a duration of 2 ticks.

The opening of Beethoven’s 5th Symphony would be written as:

['r4:2', 'g', 'g', 'g', 'eb:8', 'r:2', 'f', 'f', 'f', 'd:8']

Example#

from microbit import *
import music

melody = ["r4:2", "g", "g", "g", "eb:8", "r:2", "f", "f", "f", "d:8"]

music.play(melody)
