Languages for For Live Coding. The ones with community links are probably a good place for beginners.
- SuperCollider (community | examples) - C and smalltalk based language, for live coding sound synthesis and musical patterns via JITLib and GraphicsSpace
- ChucK (community) - strongly timed on-the-fly language featuring the Audicle and miniAudicle
- fluxus (community | examples)- Scheme based, centres around game engine, primarily for VJing but has a secret synthesiser
- Impromptu (community | examples)
- packet forth
- musique littérale, built with Quoth, in turn built with Squeak
- noisepattern (part of http://www.pawfal.org/Software/livenoisetools/ )
- Ruby(druby,irb,rjb) | JSyn (Client-Server)
- Flaxus, Toplap flash based application
- SSCLib built with SuperCollider for live slow coding
- ixi lang - A high level live coding language built on top of SuperCollider. More info on the ixilang page.
- field - A hybrid development environment for making digital art
- context free music language (cfml) - a library/sublanguage for Impromptu
- Extempore (community) - A live-coding environment and which borrows a core foundation from the Impromptu environment

- Music-As-Data - An open source language for live programming music in Clojure
- LuaAV - Real-time audiovisual scripting environment using Lua
- clive - live code JACK audio DSP callbacks in C, with auto git commit / recompile / reload / rerun on the fly, memory state preserved between reloads, colourized diffs and error messsages
- tracker.el - work-in-progress emacs-based tracker-like sequencer using elisp code to generate events
- perl-live - emacs+perl live coding environment
