A text-based programming language for music composition.

Alda is an innovative, text-based programming language specifically designed for music composition. By removing the need for heavy digital audio workstations (DAWs) or complex graphical interfaces, Alda allows users to write and play back music using only a standard text editor and a command-line interface. Its syntax is intuitive and markup-like, deliberately engineered to be accessible for musicians with zero programming background, while also catering to software engineers who lack formal musical training. A key feature of Alda is its interactive Read-Eval-Print Loop (REPL), which empowers users to enter code and hear the musical results in real time, making it an excellent tool for live coding performances and immediate prototyping. Furthermore, Alda seamlessly supports programmatic music writing, unlocking limitless potential for algorithmic and generative composition. Out of the box, it provides access to the complete General MIDI Sound Set, offering a vast array of instruments without requiring external plugins. Open-source and constantly evolving, Alda perfectly balances aesthetics, flexibility, and ease of use for the modern textual composer.

A customized parser that translates simplified plain text representations of notes, octaves, and durations into timed MIDI events.
A persistent terminal session that continuously reads Alda syntax, evaluates it into audio output, and prints the operational state.
Headless execution mode allowing external programming languages (like Python or Ruby) to generate Alda strings and pipe them to the CLI.
Built-in MIDI synthesizer capabilities pre-mapped to the 128 standard General MIDI instruments.
Independent instrument declaration and inline timing markers that allow multiple concurrent musical lines to be parsed cleanly from a single text file.
Install Alda via package manager or standalone binary
