hey, how do you do bassoon vibrato. I know flutes use their diaphragm and pulsate it sorta and voice vibrates their throat. How do you do vibrato on bassoon?

-hey,
okay, yeah, i`m an oboist, so i guess that`s close to bassoon....my vibrato just kind of comes out right every once in a while, it`s not a subject that can be explained over emails or forums but prolly more in person. but, diaphragm, everyone says, is what you use for your vibrato...all i can say is "practice makes perfect" and you`re gonna have to practice it if you want to get good/better....how long have you played bassoon??? well, good luck
