  A musical instrument is used to make musical sounds. Once humans moved from making sounds with their bodies — for example, by clapping—to using objects to create music from sounds, musical instruments were born. Primitive instruments were probably designed to emulate natural sounds, and their purpose was ritual rather than entertainment. The concept of melody and the artistic pursuit of musical composition were probably unknown to early players of musical instruments. A person sounding a bone flute to signal the start of a hunt does so without thought of the modern notion of "making music".
  
  Musical instruments are constructed in a broad array of styles and shapes, using many different materials. Early musical instruments were made from "found objects" such as shells and plant parts. As instruments evolved, so did the selection and quality of materials. Virtually every material in nature has been used by at least one culture to make musical instruments. One plays a musical instrument by interacting with it in some way — for example, by plucking the strings on a string instrument, striking the surface of a drum, or blowing into an animal horn.
