If you want to learn how to play guitar and sound good you will need to have a little discipline and it helps to be motivated.
You also need to understand why the Internet is such a fantastic resource for modern guitar students. There are literally thousands of internet sites about learning how to play guitar, covering all aspects of playing, from chords and scales, to sweep picking and improvisation. This is but one reason to learn guitar online. There are other reasons too, though.
Learn Different Styles
When you have a lesson with a private teacher, you will normally be restricted to learning whichever styles your teach is comfortable with. However, learning guitar online, like a Jamorama, you are able to learn practically any type of guitar playing you care to imagine.
Learn From Videos and Audio
Different people learn in different ways. Whether you do better by listening to a song before playing it, or watching someone play it carefully, the Internet can provide the resources you need. Even people who just need to learn the basics, will find detailed tutorials on all aspects of playing.
