The Skool of guitar excellence
If you can manage to form root 6 bar chords then you can easily do the same for root 5 bar chords following the same principles. Watch out though...the finger position is a bit tricky to start!
This chord is called root 5 because it is based on the 5th string or A string which is the root note for the chord.
When we use the A string as our bar, we use the A shape to form our bar chord. Therefore, the bar chord you are playing is the note (or root note) on the E string that your first finger is on. It’s that simple!
To get a minor bar chord we simply play the A minor chord shape, again keeping our first finger the fret behind.
You may have to find your own comfort zone for the fingering....see how I use my 3rd & 4th fingers to cover all 3 strings in the diagram below......
...some people can use their pinky to do all this, whatever...just be sure you can still "sound" the top e string when you strum
