Aulos
An aulos (Ancient Greek: αὐλός, plural αὐλοί, auloi[1]) or tibia (Latin) was an ancient Greek wind instrument, depicted often in art and also attested by archaeology.
Though aulos is often translated as "flute" or "double flute", it was usually a double-reeded instrument, and its sound—described as "penetrating, insisting and exciting"[2]—was more akin to that of the bagpipes, with a chanter and (modulated) drone.
