Add your notes to the scores

Right-click on a place where you want to leave a note, or select an area of the score you want to annotate.

Attach images or videos

Get an image of any part of a sheet, reuse it anywhere

Select an image area, copy the link to the image of the selected area, and use it in a comment at another place.

Identify and annotate musical quotations

Select a section of a score you want to refer to, get a link to its image and attach the image to the place in a place that is quoting from it.

Share performance tips

Set the type of an annotation to Performance. Users can filter annotations by type and can choose to view only annotations related to the performance of a piece.

Comment on annotations by others

Add annotations in places where others have put theirs.

Tell stories about music

Use Viewer’s Javascript API to create presentations. Define a sequence of places and annotations to be shown and publish your story online for everybody to see, or use it during a presentation or in class. A score following example is available here.

Participate in a wiki-style community

See a history of all edits for all public annotations in any score. Anybody can delete any public annotation, but it doesn’t disappear from the edit history and can be restored back.

Use it in public …

Share your music knowledge with hundreds of thousands of music lovers from all over the world, who are already using the Viewer. Share your annotations with friends by sending them links like this.

… and private

Show only annotations entered by you or your friends and colleagues using filtering. Mark your annotations as private so only you can see them. As a site owner, show only annotations entered on your website.

Use tags and filters

View only relevant annotations using tags and filtering. Use arbitrary tags to fine-tune your annotations.

As a site owner you can turn off the features of the viewer you don’t need. Define optimal visual dimensions of the viewer for your circumstances. Control the viewer programmatically with a simple Javascript API (see this page's source for an example).


The viewer is cross-platform and works across all major browsers.


The viewer is translated in many languages and can automatically choose the right language for each visitor. Currently supported are English, German, French, Italian, and Russian.


The viewer code is only 80 kilobytes. Instantly open scores of arbitrary size.


The Viewer is hosted on Google's infrastructure. The annotations are exported and published daily and can be mirrored, so they won’t disappear due to software or hardware errors.
