Flat

Music notation software for composing, collaborating, and publishing sheet music.

Flat is music notation software for composing, editing, and publishing sheet music on the web, Mac, Windows, iOS, and Android. Scores sync across devices, and work can continue offline with changes synchronized when back online. It supports real-time collaboration, letting multiple users edit the same score simultaneously.

The editor includes a complete notation suite with guitar tablature, MIDI composition, MusicXML/MIDI import and export, PDF import, automated transpositions, customizable layouts, styles, templates, and notations. Playback offers 180+ instruments including HQ studio instruments, advanced playback controls, and audio uploads from YouTube, Vimeo, SoundCloud, and MP3. Other features include complete version history, customizable shortcuts, and an embeddable interactive sheet music element. Flat for Education adds classes, assignments, and integrations with Google for Education, Microsoft Office 365, and Canvas.

Flat is available as a free Basic plan limited to 15 scores with 30 instruments and logo-marked exports. Flat Power, offered as monthly, yearly, or lifetime options, removes score limits and unlocks the full instrument library, advanced playback, custom instruments, and unrestricted exports. Flat for Education is packaged separately with a one-month free trial.
