Although a member of the woodwind family, modern flutes are mostly made from metal.
The earliest flutes date back over 35,000 years making them one of the oldest instruments in the world. They have been made out of lots of different materials including wood, bone, ivory, silver and even gold.
The sound is produced by blowing across the hole in the head joint, similar to how you make a sound by blowing across the top of a bottle.
The notes are changed by covering different combinations of holes which effectively make the pipe longer or shorter.
Flutes are found in woodwind groups, concert bands and symphony orchestras, as well as big bands and jazz groups.
