Guitar Super System

When practicing I strive for pushing the string down into the fretboard with the fleshy tip just slightly under the edge of the fingernail. Leaving the finger pointing into the fretboard at a 90 degree angle. This seems good if I want to leave neighboring strings resonating. However, if I don't want that, I tend to get unwanted noise from those strings. It also works poorly with bending since the fingernail will strike the string above. It is also uncomfortable when playing while standing unless I have a really short strap.

I see a lot of people playing with their fingers a lot more "flat" (45 degree angle or less) against the fretboard. But have been advised that the way described above is the more propper/cleaner technique. Hence I have been using it when I practice not to learn bad habits.

What would you recommend here; should i stick with this or adjust to a more relaxed and comfortable angle? What are the long term implications in the development of playing style here?

I think it has to do with preferred personal style. If you like keeping your thumb hooked over the top of the fretboard, like Tyler does, it might be harder to NOT have more of an angle on your fingers. Players like Bernth like to keep their thumb strictly behind the fretboard, making it easier to have any angle you want and attain super shred speeds. Some players like to have more of angle to actually help mute unwanted string noise from adjacent strings. But I'm a newb as well, and this is all just based on what i've watched from various youtuber guitarists.

I'd think it depends on what you are playing at that point in the song. Am I doing barre chords? Thumb behind the neck and fingers parallel with the frets. Playing chords with Hendrix-esque flourishes? Thumb is wrapped all the way around and fretting the low E. Doing a high string solo? Fingers are usually at a 45 degree angle and I'm fretting almost like you'd fret a violin.

Have you seen a video of a 'favorite' guitarist who frets like you do? Then good chance you can make it work for you as well :)

I lost a fretting hand index finger top joint. I play a barre type fingering simply because I cant articulate enough to use the "tip". Ive heard all kinds of theories. Much of what makes you the best player you can be is to play in a way you find natural for you. After hearing a lot of advice and concepts I say do you.
