This is a list of notable programming languages optimized for sound production, algorithmic composition, and sound synthesis.

• ABC notation, a language for notating music using the ASCII character set
• Bol Processor, a model of formal grammars enriched with polymetric expressions for the representation of time structures
• ChucK, strongly timed, concurrent, and on-the-fly audio programming language
• Real-time Cmix, a MUSIC-N synthesis language somewhat similar to Csound
• Cmajor, a high-performance JIT-compiled C-style language for DSP
• Common Lisp Music (CLM), a music synthesis and signal processing package in the Music V family
• Csound, a MUSIC-N synthesis language released under the LGPL with many available unit generators
