This wraps MuseScore 4's command line interface so you can transpose scores, extract individual parts, and export to PDF, MP3, PNG, MIDI, MusicXML, or even Braille without opening the GUI. It handles both semitone and diatonic transposition, lets you add or remove instruments programmatically, and includes session management with undo/redo. The JSON output mode makes it straightforward to parse results in scripts. If you're building music education tools, batch processing sheet music, or generating transposed parts for different instruments, this gives you full notation software capabilities from code. Just needs MuseScore 4 installed locally.
