(Continues from part 1...) Exactly the same process works with the E minor chord - again the root note is on the E string. And the same with the seventh shape but with one optional extra note (see video).
Again, because it is based on e shape the root note is always found on the E string.
So to summarise: We have three E shaped barre chords -- Major, Min and seventh.
And because they are based on the open E chords we always name them according to the note held down on the E string.
Now there are times when we want say C# or Eb barre chord and using the E shape means that this is rather high up the neck -- harder to play and doesn't sound that good, so it helps to have alternative shapes and that is where the A shapes come in.
A Major, A Minor and A7 (including optional note)
So I hope that will help you sort out your barre chord names.
As far as practicing goes I suggest starting out with the E Major barre chord shape and practice moving it through this sequence..

You may recognise that as the opening line of Otis Redding's Dock of the Bay --which is the song that originally persuaded me it was worthwhile learning barre chords!
So that's how to break through the barre chord barrier. In the next lesson I'll show you round a few more of my favourite barre chord based songs and also introduce you to some of the more exotic barre chord varieties! See you then! Meanwhile Practice little and often!
