How I became a Mute Maker, By Denis Wick
My long-suffering wife said, “You’re just never satisfied!”. Many a true word is spoken in exasperation. I had tentatively suggested, in about 1969, that somebody ought to design mutes that actually played in tune and worked in every register. We had been recording film music with Bernard Herrmann, who had helped to make all those Hitchcock films such a success. He was contemptuous of the old fibre mutes that I and my LSO trombone section were using. He called them "psychological mutes” and we knew what he meant.
