Notationilla

Notationilla is a modular, open-source framework for music notation and score processing. It provides an engraving engine, a scene graph of musical elements, and a scripting interface to create, edit, and render scores.

The name combines "notation" with the diminutive suffix -illa, signaling a compact, approachable toolkit for notation tasks.

Notationilla comprises a core engraving engine, a glyph and font system, a scene-graph representation of staves, notes, and symbols, and a plugin-based extension model. The system emphasizes deterministic rendering and flexible layout rules.

It supports import and export of standard notation formats such as MusicXML and LilyPond, can render to SVG, PNG, and PDF, and includes a MIDI/audio backend for playback and score animation.

Notationilla is developed by an international community of contributors and released under an open-source license. Development is coordinated via public repositories and issue trackers, with guidelines for contribution and code of conduct.

The project targets composers, music educators, researchers, and software developers who require flexible notation rendering, batch conversion, or custom engraving rules. Typical workflows include score conversion, layout customization, and automated score generation from data.

In practice, Notationilla is viewed as a versatile tool that complements existing systems by offering a programmable engraving workflow and extensibility for research and education.
