I am new to classical guitar and wasn't aware of sizing the guitar with reference to my hand size.
I bought a typical guitar with my index finger just fit the width of the fret. But when I try the bar exercises, it's hard to hit all the strings for a good sound, especially the 4th string where the joint sits. I wonder
1. Is there any exercise for increasing my ability to control my fingers such that when I "touch" the strings, I really am "hitting" the string?
2. Is it ok if I am not able to hit all the strings at one time? But then I will need to rest my joint on the string I don't have to hit, which may lead to an obvious shift of my left hand on the fret. Would that be normal?
