Ever heard of Bongos? If you see two small open-ended drums that are joined together, that's what they are. I used to call them twin drums when I was a child. These are specialty drums and they have been around since the existence of African tribes. Back then, these drums were popular because of cha-cha songs but today, these drums are used in all sorts of music and they are mostly used as a percussion instrument. If you have listened to the music of Ricky Martin; bongos were used in all his music. The Cubans were the ones who popularized the use of bongos but they actually originated in Africa as I mentioned earlier.
