In the beginning, people had only their voices to create music with. After time, someone had a spectacular idea that they could try to produce sound on certain items and provide further entertainment for themselves. One of the first of these experiments was a conch shell. People found out that by blowing into one end of the shell, while buzzing their lips, a sound very much like a modern trumpet's, came out.
In fact, a conch shell was one of the first brass family instruments produced, mostly resembling a trumpet. It began to be used in religious ceremonies and to call others to assemblies and the like. Past peoples continued their search of musical instruments and discovered that a ram's horn would produce a sound very much like a conch shell's. The ram's horn began to be used frequently as well, mostly on hunts.
