An aeneator who blew a buccina was called a "buccinator" or "bucinator" ().

== Design == It was originally designed as a tube made of either bronze or shells. However, as time went on more materials started to be used. It measured in length, of narrow cylindrical bore, and played by means of a cup-shaped mouthpiece. The tube is bent round upon itself from the mouthpiece to the bell in the shape of a broad C and is strengthened by means of a bar across the curve, which the performer grasps while playing to steady the instrument; the bell curves over his head or shoulder.
