A compact text-based format for encoding instrumental music is called MusicXML. It is a widely used format that can be easily parsed and played back by computers. MusicXML allows users to represent the details of a musical score, including notation, pitch, rhythm, and other performance information. It is a popular choice among musicians, composers, and music software developers because of its ability to accurately capture the nuances of a musical score.
Here is a python script that can take a MusicXML file as a command line argument and produce realtime audio output using pygame:
import sys import music21 import pygame from pygame.locals import * # Get the MusicXML file from the command line argument if len(sys.argv) != 2: print('Please provide a MusicXML file as a command line argument') sys.exit(1) music_xml_file = sys.argv # Convert the MusicXML file to a MIDI file using music21 midi_file = music21.converter.parse(music_xml_file).write('midi') # Initialize pygame pygame.init() pygame.mixer.init() # Load the MIDI file and play it pygame.mixer.music.load(midi_file) pygame.mixer.music.play() # Wait for the playback to finish before exiting clock = pygame.time.Clock() while pygame.mixer.music.get_busy(): clock.tick(30)
The script first imports the necessary modules and parses the MusicXML file from the command line argument. It then uses the
music21module to convert the MusicXML file to a MIDI file.
Next, it initializes
pygameand loads the MIDI file using
pygame.mixer.music.load(). It then plays the MIDI file using
Finally, the script waits for the playback to finish before exiting using
pygame.time.Clock().tick()`. This ensures that the script does not exit until the audio playback is complete.
