Flat: Sheet Music Editor

Flat is a professional music notation app for writing scores, arranging music, and preparing parts. Write, edit and play back scores for any instrumentation - orchestral, chamber, choral, jazz, marching band or mixed ensemble - on your Mac, and keep your full library in sync across desktop, browser and mobile devices.

COMPOSE ON YOUR MAC. SYNC WITH FLAT POWER.

Write and edit your scores locally, save them on your Mac, and export when you're ready. With Flat Power (premium), your scores sync automatically so your full library stays connected across all your devices. You can use your subscription with your Flat account on iPhone, iPad and in your web browser.

BETTER AUDIO PLAYBACK ON DESKTOP

The Mac app includes higher-quality soundfonts for free instruments, so playback sounds closer to a real ensemble than in the browser version. Flat Power subscribers can go further with premium instrument libraries plus per-part volume and reverb controls.
