One weekend a friend asked me to pick him up a six pack. I suggested he buy a six pack of piano lessons from me instead. "If you can't play the blues like a pro in 6 weeks I'll pay for your six pack." To my surprise he did. With a limited background in piano he is now happily playing the blues and says it's good downtime relaxation from his job. Consequently, I retained concept 6 Pack of Lessons and I profess, if you practise earnestly you can play the blues like a pro in just 6 weeks too.
