Do you know that the New York Stock Exchange bell ring sound is trademarked by NYSE Group, Inc.? The description of the sound of the bell for the NYSE’s trademark registration is “the mark consists of the sound of a brass bell tuned to the pitch D, but with an overtone of D-sharp, struck nine times at a brisk tempo, with the final tone allowed to ring until the sound decays naturally. The rhythmic pattern is eight 16th notes and a quarter note; the total duration, from the striking of the first tone to the end of the decay on the final one, is just over 3 seconds.”
