In this guitar lesson, you’ll learn the four reasons why fretting goes wrong on acoustic guitar.  Just to make sure we’re clear, the frets are the metal line that run through the guitar.  Their job is to define the pitch of the string when the string is held against the fret.  It basically does the job that the nut does, defining the length of the string and therefore the pitch.  The shorter the string, the higher the pitch.  the longer the string, the higher the pitch.  Therefore, it is important to make sure when we fret the note we’re doing a job as good as the nut does.  The best way to do this is to use the tip of the finger.  If you’ve done the job correctly is should sound as good as the open string. 

There are only four reasons this ever goes wrong:

1. Not using enough pressure.
2. Being on top of the fret.  The best place is right behind. 
3. Being too far away from the fret.
4. Obscuring a string with the back of your finger.
