To which instrument classification does the Roman tuba belong?
You are correct; the Roman military Trumpet was about four foot
in length, and was used as a military signal trumpet. It was
usually made from copper or iron and was a conical bore straight
tube that came in three pieces with a mouthpiece. Although the
Roman tuba (trumpet) was used at sacrifices, processions, triumphal
processions and funerals, it was primarily used to announce troop
movements during battle. Classifications range from 'wind' to
'brass' to 'aerophone' and it was intended to be played as loudly
as possible.
