Guitar positions are labeled by where your first (pointer) finger is. So far, everything we have done has been in the first position (since our first finger has always been in the first fret). When you slide your hand down the neck and put your first finger in the second fret, you are in second position.
Here are a few things to keep in mind when changing positions:
The Left Hand Doesn’t Hold the Guitar: You may remember from 1-2-3-wave (all the way back in book I) that your left hand doesn’t hold the guitar; this is so that you can easily move between different positions on the fretboard.
The Thumb Stays Behind the Neck Between the First and Second Finger: The thumb follows the hand when it moves and stays in the same place relative to the other fingers in the new position.
One Finger Per Fret: This means in second position, you will fret the 5th fret with your pinky. It may take some time to build up the strength, but remind your child that it took time for their other fingers to get strong too.
Commit to the Shift: If you are going to be in second position: be in second position. Commit to it. Don’t try to kind of reach for it, really move your whole hand and be in second position. Then when it is time for first position, move back with the same conviction. Many problems young guitarists have with positions come from trying to kinda-sort-of shift.
Take Advantage of Open Strings: Use the times when you are playing open strings to set up your shifts. In this case, start setting up your shift when you play the open E string.
