My son gave me a guitar for retirement. Plunking around on my own got me nowhere and I was going to go to a local place that provides music lessons... until I saw TAC on Facebook. The 5-day challenge convinced me to join, and I know I am now better off than I would with face-to-face lessons.Because I am new, older, and slower to learn, I struggle with picking, fretting and getting clean notes. So, I love the speed control on the play to help me practice each day. Frustrated, but UNDETERRED and I am slowing "winning" each day.
