How to Score in the Art Racket
summary
Demonstrates an embeddable front end that turns score annotations into real code: MuseScore + Tonart in Racket exports MusicXML, parses performance-direction text into Tonart forms, and uses Racket’s module system so score bindings become require/provide modules. Built a MusicXML parser and a registration library that maps to MIDI for a pipe organ; live demo plays organ manuals and registrations, mixes themes from different modules, and generally works despite some AV hiccups. MusicXML export and parser and organ registration as code.
