Ossia
Your sheet music, annotated.
Write on scores with Apple Pencil or mouse. Built for musicians who want GoodNotes precision on their actual sheet music.
Free · Works on iPad and desktop · Add to Home Screen for the full-app feel
Write naturally
Fountain pen, pencil, brush, highlighter — pressure, tilt, and palm rejection with Apple Pencil.
Shapes that snap
Draw and hold — slurs, hairpins, brackets, and arrows become clean, movable shapes.
Score analysis
Ossia reads your PDF and stamps chord guesses right above every bar. One tap.
Music stamps
Staves, clefs, time signatures, Roman numerals, tables — each explains itself on hover.
Select & transform
Lasso anything, then move, scale, rotate, duplicate, or recolor it. Undo reverses everything.
Precision metronome
Web Audio accuracy, tap tempo, swing, and count-in. No app required.
Setlist
Order your scores for a rehearsal or concert. Navigate with a swipe or pedal.
Live sync
Open on iPad and Mac at the same time — annotations appear instantly.
Export PDF
Download your annotated score as a PDF to print or share with students.
