I think a flute looks like a metal bamboo rod with holes. But actually, it is a hollow metal tube, usually 26 inches. It has three parts: the head, the body, and the foot joint. The instrument's musical keys are attached to the body where the flutist's fingers, except for the thumb, rest on them. The thumb rests on the E flat key located at the foot joint. On the head of the flute is a specific hole through the welded lip plate for the flutist to blow air for the notes.
