Five of the best musicians who use extended technique
Five fine examples of extended techniques in recordings

Published:
Extended techniques became popular in the early 20th century, when the boundaries between classical and jazz blurred. Composers began to borrow some of the sounds heard in blues and bebop. Probably the most famous example of the first use of extended techniques is the clarinetās drawn-out trill that moves into a bent glissando at the beginning of George Gershwinās Rhapsody in Blue (1924). Extended techniques do not appeal to everyone, but the fact that we can still find new timbres from well-established instruments ā some that have barely changed in a century ā is an achievement worth celebrating.
