This Demonstration shows how to play the guitar chords for about 350 different notes. The program is designed to support any additional note. Roman digits at the left hand line are fret numbers (the frets are the metal lines crossing the guitar's strings to produce a specific sound). An "X" on the top of a string means that it is not to be played. An empty circle on the top of a string means that it is to be played. The "next" button works when other ways to play the same note have been included in the program.
