sentences:  (De Re Militari, Book II)
  Like the Greek "salpinx" the Roman trumpets were not regarded as musical instruments.Among the tems used to describe the tone of the "tuba", for instance, were "horribilis" (“horrible”), "terribilis" (“terrible”), "raucus" (“raucous”), "rudis" (“coarse”), "strepens" (“noisy”) and "stridulus" (“shrieking”).When sounding their instruments, the "tubicines" sometimes girded their cheeks with the "capistrum" (“muzzle”) which "aulos" (“flute”) players used to prevent their cheeks from being puffed out unduly.
