Buccina

An aeneator who blew a buccina was called a "buccinator" or "bucinator" (Latin: buccinātor, būcinātor).

[1] It measured 3.4 to 3.7 meters (11 to 12 ft) in length, of narrow cylindrical bore, and played by means of a cup-shaped mouthpiece.

[3] The buccina was used for the announcement of night watches, to summon soldiers by means of the special signal known as classicum, and to give orders.

[3][5] In the final section of his orchestral work Pini di Roma (Pines of Rome), Respighi calls for six instruments of different ranges notated as "Buccine" (Italian plural), although he expected them to be played on modern saxhorns or flugelhorns.

Both instruments were first used in the music that François Joseph Gossec composed for the translation of the remains of Voltaire to the Pantheon on 11 July 1791.
