Have you ever played a Brass instument.?
Like a Trumpet, or Tuba, or even a Sousaphone?
You gotta vibrate the lips, and change tones by changing the shape of your palate/toungue..You'll know you are doing it right...and you have the
right resonance, when your brain vibrates (..Which I believe is the intention of the instument.), and the sound projects from the instument, when it
ceases to seem to come from inside..
You can practice with the carboard tube that giftwrap paper comes with..
