Yes, ArtistWorks is happy to offer free backing tracks and tablature/notation as a resource for each of our subscription plans. These resources can be found under the "Study Materials" tab in your enrolled school.
Backing tracks and tablature can be downloaded and saved to your computer for use on your own time. Most of the music schools offer downloadable tablature or standard notation as part of the lessons.
Note: Not all of the lessons offer study materials. It depends on what the instructor has provided us with and feels needs supplemental material.
