I graduaded in Russia as folk string instrumentalist at conservatory. At the child school i studied folk and guitar. Now I have 20 years of practice and concerts with guitar. As I studied all vectors of music at conservatory, I have a main vision of music. Where it stars and in what direction it flies.
We can learn not only tabs and chords (at that point we can stop, of course, if you want to), but also tonality, rhythms of styles. This will help you be able to catch up any song you may listen for the first time.
