Watch the Beyond 21: Songs online guitar lesson by Ravi from Learn Guitar in 21 Days
If you've completed the 21 day program, you really do know enough to take on hundreds of songs, which in itself is great! However, that can be like cable TV: It doesn't really matter how many channels you have if there's nothing on that you actually want to watch. Depending on the music that you prefer, this could be the case with you if you've tried to play a song that has an unfamiliar chord in it OR you feel otherwise unprepared to play that particular song.
So, in these following video lessons, you'll learn more open position chords, moveable barre chords, how to read chord charts and how to work with published song books and lyric sheets that you download from the Internet.
Once you've progressed through these additional lessons, there will really be nothing stopping you from building a repertoire of thousands of YOUR own favorite songs!.
