SmartMusic collects each piece of music the first time you select to Open it, and then stores it locally on your computer. After you've disconnected from the Internet, you'll find these titles in the left side under My Library. Method books will only download the specific exercise you open. To ensure the entire book is downloaded, double-click the book from My Library and choose All from the top of the screen.
SmartMusic does require an internet connection for continued use. However, you can continue to access your downloaded library for 48 hours after disconnecting, as long as you remain logged into the program. Please note that most of SmartMusic will require an active internet connection at all times, so pages outside of My Library will not open while offline.
