Had the day off yesterday, was able to squeeze in two 15-minute practices in one day, for the first time.
Unfortunately, I feel like I'm hitting a plateau. I'm doing the chromatic and E Phrygian scales correctly, but slowly, and I've memorized the 6 chords I know so far. However, I'm playing the notes very, very slowly, and I'm not good at switching between chords yet. Perhaps it's time to go to Lesson 3 and learn some more chords.
For my "free practice," I worked on the lead part from "Day Tripper." It's really catchy, pretty easy to play by ear, and uses (at least) four strings of the guitar. So it's a good one to learn the strings and to learn the individual notes on the strings. It's also fun to play.
I also re-tuned my guitar yesterday. Since I don't have a guitar stand, every time I take my guitar in and out of its case, it gets a little more out of tune. But it was much faster to re-tune it now that I've memorized the string names. I can just plunk out the note on my electronic keyboard, and not have to take 2 minutes figuring out which string corresponds to which note.
