Removed the clanker from the original and made a stick for hitting it. It generates unique notes depending on which side of the bell you hit and with which surface of the stick you hit it. The original was/is acoustically perfect, which is why I never refined the shape much. This adds the ability to truly play the cowbell so I think it is an excellent entry in the musical instruments contest.
