My friend and classical guitar blogger Chris Davis recently created a free eBook for learning the notes on the guitar fretboard. If you’ve been visiting this site for any length of time, you know how important I feel learning the notes on the fretboard is for any guitarist.
At 15 pages, it’s a relatively short book, but it’s not short on content. Chris provides relational maps on how the notes fit together, which can help you better visualize the fretboard. I recommend checking out Chris’s book if you’re trying to learn the guitar.
