Many professional classical musicians of all sorts of instruments will practice 6-8 hours per day or more. Whether that's necessary or not is up for debate. Either way, many of them have an almost obsessive relationship with music and their instrument -- at least at the highest levels -- which means they probably want to be playing that much. I was wise enough at the early age of 12 or so to realize that whatever that "commitment" gene was, I didn't have it, so I kept piano a personal passion rather than try to go to school for it like my parents wanted.
