Here's a really fun, challenging guitar lesson for intermediate/advanced guitarists. Too frequently, seventh chord arpeggios sound predictable and stock. By mastering these shapes (or even just one of them!), you'll instantly sound super hip when you throw them into your lead guitar improvisations.
If you have questions or need help with it, just let me know! If you're in the Fort Worth area, we can meet to go over it, too. ;)
