Fifes are small, high-pitched flutes that are often used in military bands. They are commonly referred to as piccolos or flageolets, as these terms are used interchangeably in many parts of the world. Other synonyms for fifes include tin whistles, shrills, and sopranos. The term fipple flute is also used to describe this instrument, as it has a wooden block (or "fipple") that directs the air flow into the sound chamber. Fife and drum corps, which feature both fifes and drums, are typically associated with military or colonial-era music. While the use of fife has declined in modern times, it's still an essential part of the musical heritage.
