Yes I know it's airflow; but it's not just airflow, as the sax can also be blown without making an sound. The airflow makes the reed vibrate, and the reed makes the airflow vibrate???? Which comes first?
Is the answer that the airspeed through the narrow opening of the mouthpiece produces enough low pressure to bend the reed and start the vibration?
Exactly how does "supporting the breath", or breathing from the belly help to make the reed vibrate? Does it somehow increase airspeed?
Secondly how does lip pressure alter pitch? It doesn't shorten the conical tube, so why does the pitch go up so much?
I was just wondering if someone could give a simple technical answer please
Because I keep wondering.
