Identifying Duplicate Pitches and Octaves
Part I - Identifying Duplicate Pitches
By having the ability to identify duplicate pitches and octaves on the guitar neck, you have more control over the guitar and your playing. In the lesson on tuning your guitar, there has already been a discussion on duplicate pitches on different strings, it is the most basic way of tuning. For example, the fifth fret of the 6th string and the open A string should be the same exact note (the note A). By matching that pitch we can tune the two strings together. For a quick review go back to the lesson on tuning your guitar. I have also added the tuning diagram below.

Just as we have a method for tuning the guitar, we can use that same method for finding duplicate pitches on different strings. The method is as follows, move up one string and move down 5 frets, if you are moving to the B string, move down only 4 frets. The tuning diagram could be used as example with open strings. The following is an example with fretted notes.

Notice that by using this method you could replicate the pitch of the Open E string 3 other times on the guitar, 4 if you have a 24 fret guitar. These are where they would be located.
- - Open E string
- - 5th fret on the B string
- - 9th fret on the G string
- - 14th fret on the D string
- - 19th fret on the A string
- - 24th fret on the E string (on a 24 fret guitar)
