ScoreFill: Music Notation & Sheet Music

ScoreFill is an add-on for Google Docs™ and Google Slides™ that writes a short piece of music on a staff and puts it in your document or slide as a picture you can open again and change.

Write with the mouse or the keyboard: click the staff to add a note, or type its letter. Click a note to select it; another pitch above it makes a chord.
Lengths and marks: whole notes to 32nds, dots, rests, ties, sharps, flats and naturals.
The staff: treble, bass, alto or tenor clef, 15 key signatures, the common time signatures or no bar lines. Bar lines and beams are worked out as you write, and a note across a bar line is written as tied notes.
A picture in your file: in a document it goes in at the cursor, on a slide in the middle. Its alt text describes it for screen readers and holds the notes.
Change it later: select the picture and open ScoreFill, and the notes are back in the editor. Changing a snippet already in the file is always free.

Good to know. Not in this version: triplets, lyrics, chord symbols, grand staff, repeats and playback. A snippet holds up to 200 notes. If the picture’s alt text is changed or removed, the picture stays but no longer opens in ScoreFill.
