Latin Percussion "Black Beauty" Cowbell. Perhaps the most used bell in history for the "basic" sound. It was designed to have a high pitched, bright sound with a moderate overtone, and a slightly rounded playing surface to make it easy to get a good sound for every stroke. Unlike traditional cowbells used on the farm, this instrument does not have a clapper inside. For a beater, use a triangle striker or drumstick that you purchase separately.
