Guitar notes memorization system - step 2
Step two is memorizing the EF note cluster on all 6 strings.
Take each guitar fretboard chart and learn the notes on two strings at a time thoroughly before moving on.
Think of the downward edge of these graphics as the fat 6th sting is pointing at your stomach with the head of the guitar ( tuning pegs) towards your left hand. If your left handed you'll know what to do to make it right.
Ok the EF clusters on the 1st and 6th strings are really easy to memorize. Open string and the first fret for EF at the top of the neck and they repeat themselves at the 12th fret which is the octave of the open string.
