As far as reading music and fingering go, I'm a come-backer, but for sound production, I'm a newbie all over again. But this time I can hear my tone (blessedly, as a 5th grader, I never thought about it). After almost 4 months of long tones, pedal tones, dynamic exercises, articulation exercises, lip slurs, tunes - at least an hour a day, more often more - I still sound lousy. When my teacher plays, every note starts crisply and is rich, vibrant: alive. My notes sound a little fuzzy, and flat. Tentative. So, teacher's gone to Florida for a month and I can't ask him (again). His usual answer to a question on how to fix anything is "play more" (we're in New England: I'm lucky to get that much out of him). It's hard to play when you're wincing, though. So is this tone business something that usually corrects itself over time? How much time? (I've got enough sense not to ask him that, but I'd really like some idea - weeks, months, years, never if not by now....). Not everyone who wants to sing has a voice worth it - what about trumpet players?
