Description: |
| The inventor had been principal clarinetist of the Philadelphia Orchestra 1917-1922 and 1924-1930; he held the same position in the CBS Orchestra 1930-1933 and the Cleveland Orchestra 1933-1941; after a heart attack he worked as second clarinetist for the CBS Orchestra between 1942 and 1950. From 1948 to 1959 he was clarinet teacher at Julliard School of Music. He was the most influential American clarinet teacher of the twentieth century, and his playing style continues to influence orchestra clarinetists today.The invention is a reed ligature that incorporates two longitudinal metal ribs that press the center-line of the reed firmly against the table (the flat surface of the mouthpiece to which the reed is affixed). The goal is to allow the reed to vibrate more freely, especially along either edge. These ligatures were sold under the Bonade name, and a survey in the early 1970s revealed that the majority of clarinetists in American symphonies used a Bonade ligature. These were sold under various brands, including "Bonade". Most were labeled by clarinet maker G. Leblanc, Paris, France. It is uncertain whether they were manufactured in France or in Leblanc's US factory.A later version, known as the inverted ligature, put the thumbscrews on the top side of the mouthpiece rather than the underside. This variation was not patented. See also patent 3,433,113. |
