Hi Dekker
and welcome to Chordie.
What you like to listen to might be completely different to what you will play, although if making your own songs up you could be influenced a lot by what you listen to but not all the time. It is what you are comfortable playing. I love listening to heavy rock but I play a lot of folk music.
I play acoustic guitar, but i do play some heavy acoustic rock songs my own way.
As for the large hands part are they large as in big and lanky hands or large dumpy hands?
Large lanky hands mean skinny long fingers which I would think is excellent to play any guitar. Large and dumpy is more of a problem, I have what I would call large dumpy hands, but you get used to it. Everything or anything you start of doing is a new thing for your hands/fingers to get used to so it might take time to get used to the feeling of holding a guitar, especially at the neck.
I like to have a thin nexk so my hands can get right round to the strings but then it makes it harder to play the chords properly. Too thick a neck can make it easier to place your fingers on the strings but you have to move your hand more underneath to get yer hands at the strings causing more strain to the wrist.
You will have to be patient and take your time when chosing a guitar ( says me that rushes out and buys one on the same day all the time i decide i need a new one) Once you have it, practice practice all the time. Too much practice will hurt your fingers and hands. So moderate your prcatice time and try not to get too frustrated. It can come quicker to some than it does for others so dont let a week or two of getting frustrated and not being able to play something get you down. One day it will all come together.
I am sure the two of you will come to a compromise. something like some fast rock songs that she likes and you like.
good luck
Ken
ye get some that are cut out for the job and others just get by from pretending
