I read about the concept of an angled/oblique barre chord, where you use your index finger to play 2 different frets across different strings like so:
-4- 3rd
-2- 1st
-3- 1st
-4- 2nd
---
-4- 4th
(I am aware that this might be a nonsense chord, but I hope it gets the concept across)
The concept again appeared on the question Fingerstyle guitar - how to play this arpeggio? I looked around the net and found this forum post, but nothing on SE.
So, Does anyone have any practical experience/guides on how to use such a technique?
