This page is divided in three sections: Music software written in Python, Music programming in Python, and Music software supporting Python

Music software written in Python

Audio Players

• Bluemindo - Bluemindo is a really simple but powerful audio player in Python/PyGTK, using Gstreamer. Bluemindo is a free (as in freedom) software, released under GPLv3, only.

• cplay - a curses front-end for various audio players

• edna - an MP3 server, edna allows you to access your MP3 collection from any networked computer. The web pages are dynamically constructed, adjusting to directory structure and the files in those directories. This is much nicer than using simple directory indexing. Rather than directly serving up an MP3, the software serves up a playlist. This gets passed to your player (e.g. WinAmp) which turns around with an HTTP request to stream the MP3.

• Listen - Music management and playback for GNOME

• MediaCore Audio/Podcast Player and CMS - Web based CMS for music management in video, audio and podcast form. All audio, video, and podcasts added to the system are playable from any browser.

• MMA - Musical Midi Accompaniment. If you follow the above link you will find that Pymprovisator is no longer developed due to the fact that there is this similar, but more powerful GPL Python software.

• Peyote - Peyote is an audio player with friendly MC-like interface. Peyote is designed specifically for work easy with cue sheets.

• Pymprovisator - Pymprovisator is a program that emulates the program Band in a Box from PG Music. You can think in it like the electronic version of the books+CD from Jamey Aebersold. You set the basic parameters in a song: title, style, key, chords sequence,... and the program will generate a Midi file with the correct accompaniment. (dev suspended)

• Pymps - Pymps is the PYthon Music Playing System - a web based mp3/ogg jukebox. It's written in Python and utilises the PostgreSQL database.

• MusicPlayer - MusicPlayer is a high-quality music player implemented in Python, using FFmpeg and PortAudio.

• Pymserv - PyMServ is a graphical client for mserv, a music server. It is written in Python using pygtk and gconf to store prefs.

• Pytone - Pytone is a music jukebox written in Python with a curses based GUI. While providing advanced features like crossfading and multiple players, special emphasis is put on ease of use, turning PyTone into an ideal jukebox system for use at parties.

• Quod Libet - Quod Libet is a GTK+-based audio player written in Python. It lets you make playlists based on regular expressions. It lets you display and edit any tags you want in the file. And it lets you do this for all the file formats it supports -- Ogg Vorbis, FLAC, MP3, Musepack, and MOD.

• TheTurcanator - a small midi piano tutor for windows and mac. Includes CoreMIDI wrapper written in pyrex.

• LinuxBand - LinuxBand is a GUI front-end for MMA (Musical MIDI Accompaniment). Type in the chords, choose the groove and LinuxBand will play a musical accompaniment for you.

Audio Convertors

• audio-convert-mod - audio-convert-mod is a simple audio file converter that supports many formats. At just a right-click, you can convert any amount of music files to WAV, MP3, AAC, Ogg and more. audio-convert-mod was designed with the same principles as fwbackups - keeping things simple.

• SoundConverter - SoundConverter is a simple audio file converter for the GNOME desktop, using GStreamer for conversion. It can read anything GStreamer has support for, and writes to WAV, MP3, AAC, Ogg or FLAC files.

• Python Audio Tools - Python audio tools are a collection of audio handling programs which work from the command line. These include programs for CD extraction, track conversion from one audio format to another, track renaming and retagging, track identification, CD burning from tracks, and more. Supports internationalized track filenames and metadata using Unicode. Works with high-definition, multi-channel audio as well as CD-quality. Track conversion uses multiple CPUs or CPU cores if available to greatly speed the transcoding process. Track metadata can be retrieved from FreeDB, MusicBrainz or compatible servers. Audio formats supported are: WAV, AIFF, FLAC, Apple Lossless, Shorten, WavPack, MP3, MP2, M4A, Ogg Vorbis, Ogg Speex, Ogg FLAC, & Sun AU

Music Notation

• Abjad - Abjad is a Python API for Formalized Score Control. Abjad is designed to help composers build up complex pieces of music notation in an iterative and incremental way. You can use Abjad to create a symbolic representation of all the notes, rests, staves, nested rhythms, beams, slurs and other notational elements in any score. Because Abjad wraps the powerful LilyPond music notation package, you can use Abjad to control extremely fine-grained typographic details of all elements of any score.

• Frescobaldi - is a LilyPond music score editor written in Python using PyQt4 and PyKDE4. Clicking a button runs LilyPond on the current document and displays the PDF in a preview window. There are some nice editing tools and a powerful score wizard to quickly setup a template score.

• mingus - mingus is an advanced music theory and notation package for Python. It can be used to play around with music theory, to build editors, educational tools and other applications that need to process music. It can also be used to create sheet music with LilyPond and do automated musicological analysis.

• Kodou - Kodou is a small package for algorithmic music notation which runs on top of the LilyPond compiler. It has been designed with the goal of being as minimalistic as possible, yet allowing creation of complex musical structures. It's public API consists of only two objects: a class Part (representing a musical line which itself could be mono- or polyphonic) and a main processing function kodou. Kodou's main strength however lies in it's treatment of time: rhythm is not constructed dependent on duration, but from points (notes/chords) alongside of a timeline and as such as a function of time. Setting variant durations other than the ones imposed by Kodou is possible.

• Partitura - Partitura is a Python package for working with symbolic musical information. It supports loading from and exporting to MusicXML and MIDI files. It also supports loading from Humdrum kern and MEI. It is designed to be light-weight and flexible.

Musical Analysis

• music21 - a toolkit developed at MIT for computational musicology, music theory, and generative composition. Provides expandable objects and methods for most common theoretical problems. Supports music import via MusicXML, Humdrum/Kern, Musedata, ABC, and MIDI, output via MusicXML, Lilypond, and MIDI, and can easily integrate with notation editors (Finale, Sibelius, or MuseScore) and other audio and DAW software (via MIDI).

• pcsets - Pitch Class Sets are a mathematical model for analyzing and composing music.

• PyOracle - Module for Audio Oracle and Factor Oracle Musical Analysis.

• pyHarmonyUI - is a python-based tool designed to provide a series of tools - it is based on an open source lib named pyHarmonyTooling
