I'm trying to muddle my way through fundamentals. In the first lesson for chords, it says we'll be learning the C mag. chord and the G mag. chord. The second one says we'll learn the A min. and the E mag. Then the instructor says to practice all four and make sure we have them down; but he never goes over the G mag. or the E mag. in the video segments. Also, in the learning the notes on the various strings...it says we're going to learn the notes on the 1st and 2nd string, but all that is talked about is the 1st string and nothing on the 2nd. Same w/ the 4th and 5th string...etc. Maybe I'm just missing something but it seems like half of the lessons are missing. What gives???
