Music Concept Video #1: Playing the Major Scale on a Bass in All 12 Keys

One of my New Year's Resolutions is to make one video a week that covers a music concept; this week's video demonstrates how to play major scales in all 12 keys on a bass. It's long (over 20 minutes), but if you're a beginning bass player, you may find it helpful. Feedback is appreciated.
