Neume
Version control and live collaboration
for music notation
Neume is a score editor that works the way good software works: you sketch in a draft, publish named versions, and see note-by-note history. You can also write together in a live shared score where every change knows its author.
It's free and there's nothing to install. Try everything without an account; sign in when you want to save your work and sync it across devices.
Drafts and published versions
Sketch freely in a working draft; nothing is permanent until you publish a named version. Compare any two versions note by note, and roll back what didn't work.
Live shared scores
Invite collaborators into one score with owner, editor, and viewer roles. Everyone writes on the same draft, live; every change carries its author, and the owner decides what gets inked.
Every change attributed
History answers who wrote what, when. Filter the draft by one author, keep the context their music stands on, and set aside a collaborator's work in one reviewed action. Setting work aside stays undoable until the next publish.
Real instrument sound
About 69 sampled instruments, from orchestral strings to jazz and band, load in the background. The first press of Play sounds like the instrument, not a beep.
Fast, keyboard-first entry
Type letters to place notes, steer durations from the keys, and reach everything through one searchable command palette. Play from wherever you're working.
In your browser, anywhere
Nothing to install: the full editor runs in the browser, with a focused view, play, and browse experience on your phone. Your scores sync across devices.
Built like version control, because it is
Under the page, every score is a history of small, replayable changes. That model is what makes drafts, publishing, note-level diffs, and multi-author attribution work. Software teams have relied on it for decades; Neume applies it to the page you rehearse from.
