How do you play barre chords which are at an angle?

Question

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?

Answer 1

I think it's very hard to do on neighboring strings. I do use it occasionally between the low E and the high E (that's the easiest combination for me) when playing a major 7 chord in drop-3 voicing, with an additional major 7 on the high E string:

(from low E to high E):

5 X 6 6 5 4

where I use fingers

1 3 4 5 1

so there's an angled barre chord from the low E 5th fret to the high E 4th fret.

The chord you gave as an example - which by the way is perfectly fine, it's an Ab9sus4 - I would play with the following fingering

T 3 2 1 4

(where T is my thumb).
