I chanced upon on tv the other night an old movie of Tarzan. There was the tomtom drums of the natives that is a way of communication. The rhythm of the drums have a meaning. Based on what I know, the use of the tomtom drums for communications is not fiction. That means in the olden times the musical instruments have also some other uses. I hope this traditional communication of tribes would be revived. It would be a great novelty to be a tomtom drummer in Africa.
