Our "New Tune" Friday song is "Mystery Train." Even though it's in the Intermediate section, advanced players will enjoy it too. Download the backing track and send a video of yourself playing! But there's more...for Intermediate players: a new lesson on playing Latin-style blues in D minor. In Advanced, a lesson on a Bach Invention, playing Diminished scales over ii-V-I changes and a song I wrote called "Mellow Bird Blues." Oh, and a blues in 5/4 too. Be sure to download the backing tracks when applicable. Enjoy!
