RILM abstract: "Surveys methods of vibrato production in woodwind performance. Beginning with Jacques Martin-Hotteterre, 18th-c. authors recommended finger vibrato. In the 19th c., Anton Bernhard Furstenau mentioned finger as well as jaw and breath vibrato. Late in the century, Maximillian Schwendler proclaimed that vibrato is initiated in the larynx (throat). The 20th c. has seen the debate continue over whether vibrato is produced by the breathing and blowing apparatus or by the throat, with recent scientific experiments supporting the latter claim."
