Transverse flutes are musical instruments that produce sound by blowing air across a hole in the side of the tube. They are typically made of metal, wood, or plastic and have a series of keys that allow players to change the pitch. The player holds the flute horizontally, hence the name "transverse." These instruments are commonly used in various music genres, including classical, jazz, and folk. Famous composers like Wolfgang Amadeus Mozart and Jacques Ibert have written pieces specifically for the transverse flute, showcasing its versatility and expressive capabilities.
