Sheetmusic4J :: A Java (FX) library for rendering and interacting with sheet music.
Further technical information about this project can be found on sheetmusic4j.com.
Sheetmusic4J requires Java 21 or higher.
Modules
Module<br>Description<br>JavaFX dependency
core<br>Core music data model (Score, Part, Measure, Note, Chord, Rest, Clef, KeySignature, TimeSignature) plus MusicXML and MIDI import/export<br>No
engraving<br>Framework-agnostic layout engine that turns a Score into a positioned LayoutResult (staves, measures, glyph placements)<br>No
fxviewer<br>JavaFX Canvas rendering of a LayoutResult using a SMuFL-compliant music font<br>Yes
fxdemo<br>Standalone JavaFX demo application for loading and inspecting scores<br>Yes
Sheetmusic Terminology
See docs/NOTATION_ELEMENTS.md for a visual glossary of the notation elements Sheetmusic4J<br>renders, so you can point at something in a screenshot and know exactly which class/method is responsible for it.
Core
Loading and saving of MusicXML 4.0 files, see https://www.musicxml.com/for-developers/
Importing and exporting MIDI files (javax.sound.midi)
ScoreFile convenience facade that dispatches to the right reader/writer based on file extension (.musicxml,<br>.xml, .mxl, .mid, .midi)
Testfiles from https://www.musicxml.com/music-in-musicxml/example-set/
Engraving
Pure layout math (no JavaFX) that positions staves, measures, clefs, and notes from a Score, so it can be<br>unit-tested headlessly and reused by any renderer
FX Viewer
SheetView, a JavaFX Region that renders a Score on a Canvas
Drawing logic is shared with headless test rendering through a RenderSurface abstraction
FX Demo
Opens MusicXML/MIDI files and displays a debug/inspection pane alongside the rendered score
Shows a companion PDF side-by-side (via pdfviewfx) when<br>one exists next to the loaded file with the same base name
Requirements
Java 21
Maven 3.9+
Build
mvn clean install
Run the demo
mvn -pl fxdemo javafx:run
Status
Module structure, domain model, MusicXML/MIDI I/O, layout engine, JavaFX rendering, and the demo app are in place;<br>rendering fidelity and MusicXML/MIDI coverage are still being expanded.
