EDIT:I just noticed how big my post was. I suggest clicking the link first. It's probably the most important part of my post, so you don't have to read if you lack an attention span.
About the Asian girl, classical guitar is much easier with big fingers and hands. Well at least that's what my experience so far has led me to believe. That girl must have extremely strong fingers. I also would like to comment about the practicing. In my experience almost all classical musicians are poor musicians. They spend dozens of hours, perhaps more depending on the length/intricacy of the song,
to learn just one song. They just remember the way their fingers move and repeat until it's instinct. But put a new piece of music in front of them, even a basic one, and they'll be horrible. I suspect the same from her.
There's no one standard way to play. Well I suppose there is a "correct" classical guitar technique. However, This comes from when musicians were all about discipline, strict form, etc. I feel that techniques can and should be modified to suit your needs, although if inexperienced people do it it'll probably stunt their progress. Generally classical guitar players use only upstrokes with the index and middle fingers and downstrokes with the thumb, although the standard technique has changed some recently. Many people use all 4 four fingers, especially when performing arpeggios. They also play with their skin on their finger and not their nails like many people believe. However, there are many styles of playing acoustic guitar. For example, flamenco. It is completely different. Just watch this video of the Malmsteen of classical guitar, Carlos Montoya. This man has mastered all techniques and he demonstrates them all in this one song. You can probably learn more from watching this video than any local teacher. Also notice how he taps the guitar while doing all that. Some parts look weird because he's moving faster than the camera can record/youtube sucks for streaming and keep in mind that he extremely past his prime. http://www.youtube.com/watch?v=c5zweApcVGA
I would also like to comment on the stance of the asian girl. Well I don't think stance is the proper word but i forgot what it's called. She uses an unusual stance. Is that a common stance for easterners. I have seen Indians play sitar and they sit in a similar way.
I know this post is getting long, but there is one more thing I must say. If you're used to playing with a pick and are just starting to play with fingers, you will suck. Hell, you'll probably only be able to play with one finger at a time. But you will get better very fast. Playing with fingers is not very difficult, it's just a weird transition. Usually, if you watch a classical guitarist play and ignore the notes, you will notice that his fingers aren't moving all that fast. I think what most people have trouble with is precision although it probably won't be too big of a problem for experienced electrical guitarists. Also many people use improper picking technique. They don't have teachers or bad teachers and their friends sort of just say,"Keep their fingers straight", so they keep their fingers straight all the way to their knuckles. Although it is usually taught this way, this technique makes playing with the thumb or other fingers simultaneously extremely difficult or impossible. What seems to be becoming the new standard way to play is keep your fingers straight for only the first two joints. Put you fingers perpendicular to the strings rather than at an angle like with the other technique. I suggest learning how to do it both ways. I feel this post is getting far too long and I will post more tips later on. I think I'll do one on left hand technique next.
