Excavations in the legionary fortress of Vindobona (modern-day Vienna) have revealed a specialized building dedicated to the training of military musicians. The 'Schola Buccinatorum' contains a central rehearsal hall with unique acoustic terracotta resonators embedded in the masonry to amplify and clarify the sound of brass instruments.
Archaeologists also found an adjacent workshop containing limestone molds used for casting bronze cornua and tubae, the iconic signaling instruments of the Roman army. This find highlights the professionalized nature of military music and signal-keeping in the Roman legions during the early imperial period, revealing the barracks were as much a place for technical craft as for combat training.
