Flutes of one sort or another have been played in the celtic countries for over a thousand years. The kind in use today is mainly the ‘simple-system’ flute with six holes and up to eight keys. This became popular in Ireland during the nineteenth century, when classical musicians were abandoning them for the new Boehm-system flute. Modern traditional flutes are usually copies of these early instruments, and almost always made of wood. Their cylindrical bore and wooden construction give a hollow, airy tone, softer than the classical flutes and much smoother than the tin whistle.
