Play Music Theory on Android, PC and in a browser

Start with the creator’s current links

The original product provides a web instrument and an Apple App Store listing. Follow Original creator’s web instrument ↗ and the Official App Store listing ↗ rather than an unofficial installer. This page does not distribute an APK or claim an official Android release.

The listing and web page were reviewed on September 16, 2026. Platform availability may change; the creator’s own links take precedence.

Use this playground on a desktop

Open the homepage and draw with a mouse or trackpad. Draw, Select and Erase sit above the canvas. In Select mode, click a stroke and drag it, use the arrow keys to move it, or choose a different sound. Space starts or stops playback when you are not typing in a field.

With the canvas focused, the arrow keys move a visible cursor; Enter places a note. Use Tab to move between controls. Keyboard shortcuts do not override text fields or modal dialogs.

Use this playground on a touch screen

Draw with one finger inside the canvas. Scroll using the rest of the page. The toolbar wraps rather than shrinking text, and the drawing area stays above the playback controls. If audio is silent, tap Play and check media volume before assuming the drawing failed.

Use a current version of Chrome, Safari, Firefox or Edge. Read the sound checklist.

Move a drawing between devices

Local drafts do not sync between devices. Download the editable project, or create a share link from Save & export and open it on the other device. A link holds a snapshot, not a live synchronized document. Keep the downloaded project as your backup.
