The Boehm flute is a type of concert flute designed by the German instrument maker Theobald Boehm in the 19th century. It features a system of keys that allows for greater ease of playing and improved intonation compared to earlier flutes. The Boehm system has become the standard for modern flutes used in orchestras and solo performances. This flute is typically made of metal, such as silver or gold, and has a cylindrical shape. Its design includes a series of tone holes and keys that facilitate a wide range of notes and dynamics, making it popular among both amateur and professional flutists.
