Hello. I've been "on comeback" for 3.5 yrs now after a 25-year layoff. I have a teacher but I want your opinions on this. I've found that two slightly different mouthpiece placements work reasonably well for me but for different reasons. I'd like to settle on the best placement for me and move on with practicing. Using an early-1980's era Bach 3C; the very same mpc I used 25+ years ago.
Placement #1: Nearly equal upper and lower lip. Feels like both lips are taking equal pressure. I play fairly well this way but it requires more warmup time to get a good tone. This is the placement I've used during my comeback.
Placement #2: Slightly more lower lip than upper. Still more than 1/3rd upper lip but not quite 1/2. My teacher can barely tell the difference visually between #1 and #2. With this placement my tone is good even without warmup but I still warm up carefully and patiently. Range is easier. Face is more relaxed. Feels more efficient and focused. But I wear out faster (lower lip) with placement #2. The sound starts to shut down above the staff. Feels like the lower lip is swelling more or perhaps there isn't as much room in the mpc to accommodate the swelling since the mpc is sitting slightly lower. I think this is the placement I used 25+ years ago. I was the best player in the county but endurance was my weak point. This was at least partially due to the fact that I never practiced outside of school.
For what it is worth, I get a ring on my lower lip (no cutting, bruising, etc.) with either placement but I never get any ring or mark whatsoever on my upper lip. Most players I see get an an upper ring and sometimes a ring on both lips. Need your thoughts. My teacher cannot tell the difference but the feel and performance is significantly different. I probably need a new teacher but I'd like your input. I promise I won't sue anyone for bad advice.
