Noteflight
The cloud-based standard for music notation, collaborative composition, and pedagogical assessment.

The world's most advanced automated music engraving system using programmable text-based input.
LilyPond is a powerful music engraving system, often described as the 'TeX of music.' Unlike typical WYSIWYG notation software, LilyPond functions as a compiler that transforms plain text input into beautifully engraved sheet music. Its core architecture is built on the philosophy of traditional, hand-engraved aesthetics, utilizing sophisticated algorithms for horizontal and vertical spacing, line breaking, and page layout. In the 2026 market, it remains the gold standard for high-end music publishing and academic research due to its uncompromising output quality and scriptability. The system uses GNU Guile (a Scheme implementation) as its extension language, allowing users to programmatically define notation rules and automate complex compositional tasks. This makes it a preferred backend for modern AI-driven music generation systems that require high-fidelity visual output. Its text-based nature allows for seamless integration with version control systems like Git, making it unique in the music industry for collaborative, iterative workflows and large-scale score management.
Dynamically scales the weight and proportions of musical symbols based on the staff size to maintain legibility.
The cloud-based standard for music notation, collaborative composition, and pedagogical assessment.
The world's leading open-source music notation software powered by professional-grade orchestral playback.
Advanced polyphonic audio-to-score transcription powered by deep neural recognition.
Verified feedback from the global deployment network.
Post queries, share implementation strategies, and help other users.
The entire engine is scriptable via GNU Guile, allowing users to inject custom Lisp-like code into the notation.
Uses a 'skyline' algorithm to determine the exact contours of musical objects for tight, collision-free vertical packing.
A tool that allows the embedding of LilyPond musical snippets directly into LaTeX, HTML, or Texinfo documents.
Supports arbitrary pitch alterations and custom tuning systems via programmable pitch-to-glyph mapping.
Because source files are plain text, changes can be tracked using Git with line-by-line diffs.
Built-in support for generating Braille music notation directly from musical source code.
Publishers requiring 'Urtext' quality scores that mimic the look of 19th-century hand-engraved plates.
