I've been playing for about fifteen years. My practice lapsed pretty badly last year because of a problem with my sinuses and now I'm trying to get back started. I'm not having too much trouble and seem to be making progress, but I would love any advice that will speed things up (I know be patient LOL). I still haven't managed to get back to playing many high notes, but my mid-range is good. I always had problems with low Ds in the past and I still am. I try to practice at least an hour a day and no I do not have a teacher (nor the money for one). Any advice welcome. Thanks.
