Guitarnoise.com is a guitar education site featuring free online lessons, musician columns, and theory pointers.
All the lessons include music sheets and mp3 versions of the featured songs. The site can be searched by level of ability, through the tag cloud or by directly typing what you are looking for. Also worthy to take a look at are the reviews on equipment and accessories, like training books and DVDs, which you can buy from the site’s store. This site has only recently launched its blog at Guitarnoise.com/blog, where users can take a look at the webmasters submissions. There are several forums where guitar learners join to discuss and share the joys and sorrows of learning to play music.
