Free online sheet music editor, no sign-up

Partitura is a score editor that runs right in your browser. Here is what is worth knowing before you start.

Online, nothing to install

Unlike MuseScore, Sibelius, Dorico and other desktop programs, there is nothing to download or install: it runs in the browser, on any computer.
No sign-up

There is no account to create and no login: open the page and start writing, unlike Noteflight or Flat.io.
As many scores as you like

You can keep several scores open at once, each in its own tab.
Saved in your browser

Everything is saved on your device as you write. Nothing is uploaded to any server. To keep or share a score, export it from the menu.
Free and ad-free

The site is free and has no advertising: no ads or trackers to distract you.
Built to be intuitive

We work hard to make the interface clear without explanations. Even so, the menu on the left has tutorials for every feature and a guide with all the keyboard shortcuts.

Partitura

Desktop only

Editing a score on a phone is very hard because of the small screen.

Multiple voices

Write two or more voices on the same staff, each with its own rests.
Slurs across barlines

Select two notes, even in different measures, and slur them from the menu.
Triplets

Select three eighth notes and turn them into a triplet from the context menu.
Barre chords

Mark the barre on the tablature with its fret, from start to end.
Hairpins and dynamics

Crescendo and diminuendo between two dynamics, like p and f, over any notes.
Download your score

Export to PDF, MusicXML or MIDI to print it or open it in other apps.
