Looking back several years, I ask myself what was it I needed or wanted that would have improved my learning situation. The answer is that I needed two things that I had to go outside this wonderful L&MG course. The first was to have a “pre-guitar knowledge” to prepare me. Of course, at the time I was at the highest point of enthusiasm I would have until several years later, so I was ready to plunge on and get to playing. Then, Steve, your course whetted my appetite for theory, so I bought “Eddly’s Musical Theory for Practical People,” and commenced studying while I continued to practice, and the insight improved my enjoyment. I didn’t want to have the detailed knowledge of a music major, but I did wish to know the why’s and wherefores. So, the first advice I can give is that L&MG write, publish, and provide something like “Eddly’s,” with the explanation that it is for studying apart from learning to play guitar. The one thing I’d add that “Eddly’s” is short of, is a glossary of musical terms and symbols, such as that on the Mormon Church website (If you don’t love music or like to sing, the Mormons excommunicate you).
The other thing I learned was that learning to read music is a skill apart from learning to play guitar, so I located a website called www.musictheory.com and found online drills of identifying notes. These drills facilitated my practice routine beyond the progress I would have made without them. So, Steve, I think a video game of practice reading music would be a great addition.
With or without these enhancements, your L&MG is a wonderful course. Lotsa luck.
