Notation software for the way contemporary music is written today.
ClapNote.pro is a web-based notation editor built for composers working with extended techniques, custom symbols and non-traditional forms.
Built for how composers actually work
A modern foundation for a notation engine that respects the way contemporary music is written.
Extended-technique first
A notation model designed around microtones, custom articulations and non-standard symbols — not retrofitted after the fact.
Modern editor UX
A workspace inspired by Figma, Dorico and Ableton. Fast, keyboard-driven, and made for long composing sessions.
Custom symbol library
Bring your own graphic symbols. Reuse them across scores and share them across projects.
Web MIDI & Apple Pencil
Architected for MIDI keyboards and precise pencil input on tablets — arriving in upcoming phases.
Version history
Every project keeps a history of your edits so you can compare and roll back with confidence.
Collaboration ready
Foundation built for realtime multi-user editing and score sharing in future releases.
