For the people who take lessons, I was wondering about the duration of your lessons and what you think. When I used to live in England, I took lessons by the hour. Hour-long lessons were just the standard, at least with the guys I studied with. But after I moved back to the States, I noticed that many instructors teach by the half-hour. For me, half-an-hour just isn't enough time for a quality lesson. By the time you sit down and tune up, you lose five minutes and during the last five minutes of your lesson you end up looking at your watch and getting ready to pack up. That leaves 20 minutes of real lesson time, which isn't really enough to get your mind to that absorbing state, plus you can't really ask many questions. (Of course, you can always remedy that by getting two lessons back-to-back. ) Also, how much do you guys spend on your lessons?
