I can manage a few high B-flat long tones, but they get airy-sounding pretty quickly, and eventually just cave, entirely.
Just for context...the following playing technique and gear USED TO afford me with easy-peasy high-Cs...and if necessary, solid Ds and Es. However, this no longer seems to be the case.
My approach to playing/practicing involves the following, even tho it longer results in an easy high register:
- Plenty of air
- Lots (and lots) of long tones, especially above the staff
- Two-plus hours per day on the horn, with plenty of breaks
- Scales, etudes, and excerpts
- More scales, etudes, and excerpts
- Relaxed breathing
- Aligned neck, and shoulders
- Pivoting with low/middle/high registers, like you do
- A clean, open, and warm tone in low and middle registers
- Rath R4...which practically plays itself, just sayin'
- Monette TT5 (original, pre-STC)
- (and any number of different Rath R4 lead pipes)
With all that, my high register is as thin as can be (compared to its former glory)!
I tried two 6-ish mouthpieces for a week (a Bach 6 1/2M and a Monette TT6s1). Neither helped my high register, but both killed my tone AND my low register...and both just felt WAAAY too small the entire time.
I'm toying with the idea of a slightly shallower mouthpiece (than the TT5). For instance, the TT5 Shallow (MB V3). Or perhaps a mouthpiece with a thinner rim (than the TT5), but I don't have access to any alternatives other than the Bach 6 1/2M and the TT6s1, mentioned above.
Any thoughts?
