A musical instrument is a device created or adapted to make musical sounds. In principle, any object that produces sound can be a musical instrument—it is through purpose that the object becomes a musical instrument. The history of musical instruments dates to the beginnings of human culture. Early musical instruments may have used for ritual: such as a trumpet to signal success on the hunt, or a drum in a religious ceremony. Cultures eventually developed composition and performance of melodies for entertainment. Musical instruments evolved in step with changing applications.
The date and origin of the first device considered a musical instrument is disputed. The oldest object that some scholars refer to as a musical instrument, a simple flute, dates back as far as 67,000 years. Some consensus dates early flutes to about 37,000 years ago. However, most historians believe that determining a specific time of musical instrument invention is impossible due to the subjectivity of the definition and the relative instability of materials used to make them. Many early musical instruments were made from animal skins, bone, wood, and other non-durable materials.
Musical instruments developed independently in many populated regions of the world. However, contact among civilizations caused rapid spread and adaptation of most instruments in places far from their origin. By the Middle Ages, instruments from Mesopotamia were in Maritime Southeast Asia, and Europeans played instruments from North Africa. Development in the Americas occurred at a slower pace, but cultures of North, Central, and South America shared musical instruments. By 1400, musical instrument development slowed in many areas and was dominated by the Occident.
Laos is dominated by the Lao but includes minorities of Hmong, Mien, Kmhmu, among many others. The most distinctive Lao musical instrument is a bamboo mouth organ called a khene. The instrument was supposedly invented by a woman trying to imitate the calls of the garawek bird. The woman took the new instrument to her king, and he told her it was fair, but that he wanted more. She modified the instrument and he replied "Tia nee khaen dee" (this time it was better).
