These videos are designed for guitar beginners or those with only limited guitar knowledge. They use simple chord shapes as much as possible and do not necessarily represent the way in which the song was originally played. They are designed as practice tools to supplement your other learning methods. Information is provided on screen for both right and left-handed players!
Songbird really only uses two simple chords - G major and E minor 7 - plus a G/F# as a means of connecting them smoothly. It's a great piece for beginners and a nice introduction to slightly embellished versions of chords you know.
