blowpipes
Blowpipes are simple wind instruments traditionally made from hollow tubes. They are played by blowing air through a mouthpiece, which vibrates the air column inside the tube to produce sound. The pitch can be altered by changing the embouchure, the way the player shapes their mouth, or by using finger holes along the length of the instrument if present. Some blowpipes are designed for melodic playing with keys or holes, while others are primarily percussive or used for specific sound effects.
Historically, blowpipes have been found in various cultures across the globe, often associated with indigenous peoples.
