| Well, Jorge, it's all about knowing what a centered sound sounds like, right? If you know what evey note you can play sounds like at its optimal best, you'll have no trouble because you'l always know what you're looking for.
Hearing a centered sound is like knowing what a familiar object looks like from all angles. If you can hear it your face will do what you need to do to produce it. After that, it's a question of exercising the sound every day.
