SonaRest: Custom Shoulder Rest

SonaRest

About this app

Requires a SonaRest order from sonarest.com. The app unlocks with the 12-character code in your order email.

SonaRest makes violin and viola shoulder rests shaped to the person who plays them. This app is how we measure you.

HOW IT WORKS
• Enter the code from your order email.
• Print the 2-page sheet. Cut out the board on page 2 and tape all four corners to a hardcover book.
• A helper holds the book on the player's right side, printed side facing the camera. The app guides them with rings drawn around the shoulders.
• Record two slow passes — one across, then the same arc back. It takes a few minutes.
• Send the scan. We build your rest from it, 3D-print the body in PLA with a foam pad, and ship it.
• When your scan is processed, you can see your shoulder in the app and choose where the rest sits before we print it.

PRIVACY
• Video is recorded without sound.
• The video shows the player's face. It is sent to us and used only to build the rest.
• It is not used to train AI models.
• Your face is cut out of the 3D shape we show you.
• Videos are deleted within 90 days of your rest being delivered. If a delivery date was never recorded, they are deleted within 180 days of your scan. You can ask us to delete yours sooner from the "Your data" screen.
• If you film someone else, including a child, the app asks you to confirm you have their (or their parent's) permission first.

SIZES
Every violin size from 4/4 to 1/32 and every viola size from 10" to 17".
