This chart is just a reference. The first thing you should do is learn the names of the notes on the 6th and 5th string. This is because you will need to know the names of these notes to play any moveable chords where the root is on the 6th or 5th strings. The first step is to memorize the following words of wisdom. Although it may seem stupid, make sure you know the 1st 7 letters in the alphabet forwards and backwards.
Most people have a little trouble with the backwards part.
With this information you can find any note on the neck of the guitar, as long as you know the names of the open strings. Click here for more information on the musical alphabet by guitarist Jamey Andreas.
