A musical instrument is a tool used to make music. 


As time passed, people shared new ideas. Instruments spread to far places through trade. In the city of Ur, people used harps and cymbals. 

A musical instrument is a device used to create musical sounds. 


There are many ways to play an instrument. You might pluck the strings on a string instrument. 


Finding the first instrument is a hard job for scholars. Many early tools were made of bone, wood, or skin. These materials rot away over time. This makes it hard to know exactly when music began. One famous bone flute was found in Slovenia. 

Instruments spread across the world as people met. 


Musical instruments keep changing with new technology. 


A musical instrument is any device created or adapted to produce musical sounds. While any object can become an instrument through its intended purpose, the term usually refers to specialized tools used by an instrumentalist. Humans transitioned from using their own bodies, such as clapping, to using external objects to create music. Early instruments likely emulated natural sounds and served ritualistic roles rather than pure entertainment. For example, a horn might signal a successful hunt, or a drum might accompany a religious ceremony. 
Playing an instrument involves interacting with it through specific physical actions. An instrumentalist might pluck strings on a string instrument, strike the surface of a drum, or blow air into an animal horn. As human culture evolved, the materials used for these devices changed significantly. Early makers used "found objects" like shells and plant parts. Eventually, almost every material in nature has been utilized by at least one culture to craft an instrument. 
Archaeologists face challenges when trying to date the very first musical instruments. Many prehistoric tools were made from perishable, biodegradable materials like wood, bone, or animal skins. These materials often rot away, leaving little evidence for researchers. One famous, though disputed, artifact is the Divje Babe flute found in Slovenia. 

Significant archaeological finds provide deeper insight into ancient musical complexity. In the Sumerian city of Ur, excavations by Leonard Woolley in the 1920s revealed an impressive ensemble. These items, found in graves dated between 2600 and 2500 BC, included nine lyres, two harps, a silver double flute, a sistrum, and cymbals. 

Musical instruments developed independently in many regions, but contact between civilizations caused them to spread. For instance, instruments from Mesopotamia reached maritime Southeast Asia, and Europeans played instruments from North Africa. The xylophone is a notable example of an instrument that originated in the Southeast Asian mainland and archipelago. It eventually spread to Africa, the Americas, and Europe. 
The history of instrument development is not a simple line of increasing complexity. German musicologist Curt Sachs noted that it is misleading to rank instruments by workmanship alone. Cultures have different access to raw materials and develop at different rates. For example, early slit drums required hollowing out large trees, while later versions used simple bamboo stalks. 


To organize this vast variety of tools, scholars use the discipline of organology. This is the academic study of musical instruments. The most common academic method for grouping them is the Hornbostel–Sachs system. Instead of grouping by size or material, this system classifies instruments by the specific means they use to produce sound. This allows researchers to understand the relationship between different cultures and the evolution of musical technology.
