Recently I came across a software which will help you to learn Guitar. The GCH guitar course is a program designed to help you learn to play the guitar. This unit, the 2nd, of the multimedia course, is intended for students who have played guitar for more than one year and for students who already finished the 1st unit of the course.

This course is extremely well structured. In my opinion, if you already know the basics of guitar playing, you might try and develop your guitar playing skills by using this program.
