To help memorize the fret board, use the dots, its what they're for. the first dot means 3rd fret, second dot means fith fret, third dot means ninth fret, the double dots mean 12th fret, then the next dot means 15, and the next dot means 17, and the next dot means 19(if it goes that far). Keep using the dots as aid until you memorize where the frets are, then you'll be playing wiht ease and be able to look away before too long.Yes, you can buy videos of how to play songs, just search the internet. Tabs and chords that you find on the internet are more guidlines than they are official ways to play the song.They give you an idea of how it goes, but some are accurate.Also, if the song sounds right on your guitar, but doesn't directly match the tone on the cd, it could also be that your guitar isn't tuned as high/low as it is on the guitarist's or that they are using an effect you don't have.
