aerophor
aerophor. Device (invented by Ger. flautist Bernhard Samuel and patented 1912) to help wind players. A small bellows, worked by foot, supplies wind by tube to a corner of the mouth, leaving the player free to breathe uninterruptedly through the nose. Richard Strauss called for its use in his Festliches Präludium, Op.61, erroneously describing it as aerophon, and in his Alpensinfonie, Op.64.
