When buzzing last night, no mouthpiece, I noticed that the direction of my air was almost straight down. I had never thought about it before, but we always talk about the air column moving forward through the instrument and it seems strange for my air to naturally flow almost vertically downwards. I have not had problems with tone or production, but wondered whether there is a more efficient direction for the airflow. I have quite an unconventional embouchure shape with most of the mouthpiece over the bottom lip, but with the top lip slightly infront of the bottom. Which I think forces the air downwards. Do people think about the direction of their airflow or is it simply a product of the embouchure position? How does it affect different aspects of playing, production, tone, dynamic contrast and intonation?
