A gauge for measuring the expiratory air flow pressure of an individual. The inventive device includes a main body having an extension tube removably coupled thereto. The extension tube is operable to mount various woodwind or brasswind mouthpieces in fluid communication with the main body. An aperture extends through the main body to permit the exiting of air blown through the device and includes an adjustment means for selectively closing the aperture to simulate air flow through various musical instruments. An air pressure gauge is mounted to the main body in fluid communication therewith to indicate an air flow pressure in both negative and positive directions therewithin. This helps train the respiratory muscles to inhale and exhale the air in a consistent manner which improves tone and breath control.
