I concur with all the other comments about the excellence of Bradford Werner's classical guitar website.
Discovering that website gave me the confidence to pick up a classical guitar after a 30-year hiatus. While I left classical guitar as a beginner, it is very fulfilling to return, now that I have more time to invest in the pursuit.
I have purchased some of Bradford Werner's modestly priced music books, even though I will not be using some of them for quite some time. I wanted to support the site that way. I gotta say, that as a fellow Canadian, I am so proud of this guy.
There are many online classical guitar websites, but by focusing on Bradford Werner's site and this site, I think a self-motivated player, starting anew, is well-served. Moreover, I truly enjoy having the flexibility of being able to connect with 'my' online instructors at times suitable for me, and not being committed to a time-specific scheduled music lesson and/or having to travel to that music lesson.
