If your screen size is too small, SmartMusic can't run properly. Here are a few strategies to make sure your screen is optimized for SmartMusic:
Make your Chrome browser window the size of your entire screen by using the Maximize or the Full Screen functions on your device.
Check your zoom by following these instructions. The recommended zoom setting is 100%.
If you are seeing a "Your screen is too small" message using the Chrome browser app on your iPad, please install the SmartMusic app from the App Store.
