The flute, aulos, of which there were many varieties, was a highly popular instrument, and differed in construction from the flutes and pipes of the ancient Egyptians. Instead of being blown through a hole at the side near the top it was held like a flageolet, and a vibrating reed was inserted into the mouth-piece, so that it might be more properly described as a kind of oboe or clarionet. The Greeks were accustomed to designate by the name of aulos all wind instruments of the flute and oboe kind, some of which were constructed like the flageolet or like our antiquated flûte à bec.
