“While the term “flute” refers to a broad number of instruments which are found in many different cultures, we will be exploring the history of our modern flute. There are many names for this special kind of flute. These names include: cross flute, German flute, transverse flute and flautotraverso. What is important about all of these names is that they define an instrument that is held horizontally while being played. A flute dating back to approximately 900 B.C. was found in China and called a ch’ie. To date, the oldest flutes have been found in the Swabian Alps region of Germany, and are said to have been from about 43,000 to 35,000 years ago.” From https://banddirector.com/woodwinds/flutes-piccolos/flute-history/  “Historically, flutes were most commonly made of reed, bamboo, wood, or other organic materials. They were also made of glass, bone, and nephrite. Most modern flutes are made of metal, primarily silver and nickel. Silver is less common than silver alloys. Other materials used for flutes include gold, platinum, grenadillaand copper.” From https://en.wikipedia.org/wiki/Flute
