The very first bar chord I teach people is always the Root 6 Minor chord pattern, because it is the easiest to get the hang of, and with it you can learn most of the basic principles of how bar chords work.
You’re probably familiar with the basic shape of this chord from the open E minor chord. The fingering for that chord is like this: 022000.
With a bar chord, all you’re doing is moving all those zeros to another place on the fretboard. To keep the pattern intact, you need to add to the 2’s the same number of frets you add to the 0’s. The new letter name for the chord is determined by the first note in that chord, from the 6th string. That’s why we call this a Root 6 chord; the root note is on the 6th string.
So, for example, if we move the open Em chord up to the fifth fret, we find an A there on the 5th fret of the 6th string. If you add five frets to the 022000 pattern, you get 577555 instead. That’s an A minor, root 6!
That’s the general idea behind bar chords, but if you’re still a little confused, hang in there, I explain things from a slightly different angle in the video below, and of course in FAR more detail and from multiple angles in Bar Chords Made Simple.
thanks for the lesson its great.
Practice and more for me other than that I understand what your getting at
