. In some models, the bellows contains a water reservoir and electric light bulb to ensure that the supplied air matches the temperature and humidity of the player's breath.

Reception and utilisation

Some composers took advantage of the new invention, writing music that specifically requested the use of an aerophor in performance. Notable examples include Richard Strauss's ''

technique could allow a musician to accomplish the same goal of playing indefinitely without the need for a special apparatus. Boston Symphony tuba player Paul Mattersteig made use of the device for some time, including that orchestra's December 1914 performance of Wagner's Faust Overture, and Boston's first-chair horn Bruno Jaenicke and principal oboist Georges Longy "experimented with the device with much success.""Don't Need Lungs Now; 'Aerophor' Blows for You." Cleveland (OH) Plain Dealer, 28 March 1915. Despite a generally positive reception by professional wind players at the time, the aerophor never achieved widespread use, and today is regarded as nothing more than a curiosity.
