I am enjoying TAC very much. The material is interesting and challenging. I'm certainly not bored and look forward to learning new things. I don't feel like I'm really mastering anything but I am trusting the process that consistency will ultimately provide results. Originally, I started with personal lessons, then tried a couple different types of online programs but stalled out, lost interest every time. What I like most about TAC is that the new material is different all the time, not just learning chords and transitions. Keeps me coming back!
