Knowing the notes on all strings and positions is a great challenge for any guitar player. In these exercises the guitarist fingers the same note name on each string in different positions. The sequence of notes follows the circle of fifths so that all 12 possible notes get to be played.
By clicking on a staff in the notation, you hear the guitar in solo mode. In the video however, the whole track is played by a real guitar player with a gorgeous jazzy jamtrack.
The note location exercise is included in the Guitar Lovers Studies PDF which features high graphic resolution for printing and integrated sound.
