Musical instruments

A musical instrument is an object constructed or used for the purpose of making music. In principle, anything that produces sound can serve as a musical instrument. The history of musical instruments dates back to the beginnings of human culture. The academic study of musical instruments is called organology.
The date and origin of the first device considered to be a musical instrument is the subject of modern debate. Archaeologists tend to debate the matter in terms of the validity of various physical evidence such as artifacts and cultural works. An artifact of disputed status as a musical instrument dates back as far as 67,000 old; artifacts commonly accepted to be early flutes date back as far as 37,000 years old. However, most historians believe determining a specific time of musical instrument invention to be impossible due to the subjectivity of the definition.
Musical instruments developed independently in many populated regions of the world. However, contact among civilizations resulted in the rapid spread and adaptation of most instruments in places far from their origin. By the Middle Ages, instruments from Mesopotamia could be found in the Malay Archipelago and Europeans were playing instruments from North Africa. Development in the Americas occurred at a slower pace, but cultures of North, Central, and South America shared musical instruments.
Scholars agree that there are no completely reliable methods of determining the exact chronology of musical instruments across cultures. Comparing and organizing instruments based on their complexity is misleading, since advancements in musical instruments have sometimes reduced complexity. For example, construction of early slit drums involved felling and hollowing out large trees; later slit drums
