There are many competing websites, books and DVDs available when it comes to the subject of guitar lessons for beginners. For novices it can be very difficult to know which method of guitar instruction is best especially if you have no experience whatsoever.
The classic way to learn guitar is by going to a local tutor for private lessons. This time honoured practice is still probably the best assuming you can actually find a good local tutor, there may not be one present. My first word of advice is this - just because someone is advertising a guitar lesson does not automatically mean they are a good tutor.
If you can't find the time to dedicate to a weekly lessons slot or perhaps can't even find a local teacher the internet becomes the obvious answer for most. Guitar lessons for beginners features highly on a lot of guitar websites and some of the instruction is fantastic.
