i don't have much trouble playing barred chords. (not that i play them perfectly).
I just wanted to know what the most commonly used barred chords are...

i already knew the E and A shaped barre chords, because they very much resemble the powerchords...WHO DOENS'T KNOW THOSE?!?!?!

I have a question about the C shaped barre chord:

the C shaped barre chord is quite new for me, but isn't it a Aminor shaped barre chord???

if so...you have these 3 kinds:

- Eminor
- Amajor
- Aminor

Is this all? are these all the chords that are mostly used when barring?
