SonaRest: Custom Shoulder Rest

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. • The player holds the book against their right side, printed side facing the camera, and stays still. A helper films with the phone, guided by rings the app draws 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". Questions: contact@sonarest.com
