hey just a quick question.

so just like a powerchord, a chord has the same finger position but can start on any string and fret??

i believe only on the E and A string because once you get to the b string it's different because of the difference in pitch between the G and B
#4
It depends on the chord. Barre chords may be played at any position. Open chords, not so.
#5
A powerchord is made up of the root of the scale and the fifth.

So you would use this fingering for all except the G and B strings.

You'd use this fingering for the G and B strings
