I'm a male hobbyist singer, probably somwhere between baritone and tenor.
I cannot seem to produce any sound above a #C5. I'm not talking about singing in full voice, just to squeak out anything, falsetto, headvoice, whistle, flageolet. Not on any vowel, not in lip rolls, hum, ng-sound, nothing. It seems like there is an absolutely hard ceiling there. If I look at youtube videos like this one:it seems that one should be able to produce notes above #C5 at least in a quiet manner. Here the guy is going to a bB5!! I can speak in a "mickey mouse tone", apparently that's falsetto, but that will be in the range around F4 to bB4. So maybe I cannot pass my second bridge?
Any tips on what I could practice to at least be able to silently squeak out those notes? I think if I can get the basic vocal coordination down, I can practice to have a fuller tone with vowels etc.
