Please help! I'm trying to learn guitar and my fingers are not cooperating!

Sep 10, 2019

I've been trying to learn guitar for about a week now and I've run into a slight problem. I don't know whether it's a problem with my technique or my fingers. When trying to play a G major chord (3rd fret, 1st string; 2nd fret, 5th string; 3rd fret, 6th string) I simply can't get the first string to stop buzzing. I suspect it has something to do with my finger position.

For some reason when I put pressure on my fingers they bend backwards at the last joint. My ring finger (the one that I'm using to fret the first string in that G chord) can bend about 45 degrees this way, and I can't get it to stop. I don't know whether it's because my fingers are weak and unstable, or whether it's just a weird physiological thing. Whatever the case, in all the pictures of G major chords that I see the ring finger does not seem to bend back like that, and I think that this is the reason I'm having trouble.

Is this the case, and what should I do?

I appreciate any and all help.
