Abstract
An airflow indicator providing a visually observable measure of relative airflow through a wind musical instrument which facilitates evaluation proximate the end of the instrument. This allows airflow to traverse the majority of the length of the instrument and particularly to traverse the valve section, so that actions of a player in operating the valves which impair the airflow may be seen. Some examples may be configured to minimize differences in pitch between the wind musical instrument with the airflow indicator in place, relative to the wind musical instrument without the airflow indicator.
