enables music21 to render images of musical notes

print('installing lilypond...')
!apt-get install lilypond > /dev/null

print('installing musescore...')
!sudo apt-get install musescore

converts midi files to wav files into order to play them

print('installing fluidsynth...')
!apt-get install fluidsynth > /dev/null
!cp /usr/share/sounds/sf2/FluidR3_GM.sf2 ./font.sf2

print('done!')

import music21
from IPython.display import Image, Audio

def show(music):
display(Image(str(music.write('lily.png'))))

def play(music):
filename = music.write('mid')
!fluidsynth -ni font.sf2 $filename -F $filename.wav -r 44100 > /dev/null
display(Audio(filename + '.wav'))

n = music21.note.Note('D#3')
n.duration.type = 'half'
play(n)
show(n)

Question is how to use musescore inside Collab ?
