While excessive airflow can cause the larynx to rise, most of the time
singers who use a heightened larynx put it in that position prior to the
airstream being released, even if they took a deep, low breath. This
excessive compression (as in swallowing) causes the excessive subglottal
pressure and the need for more air to be used than should be necessary. Why
do they put the larynx in a hiked up position prior to phonation? The larynx
lacks the ability to coordinate adduction without the use of suprahyoid
muscles, especially as the singer moves out of chest. It is in most cases,
not a reaction to the air, but the cause of inefficient airflow.
