A buisine (or añafil) is a type of trumpet used in the Middle Ages. It was one of the most important instruments of the period and was used by heralds and for a variety of purposes including signaling, battle cries, and court ceremonies. In terms of its shape, it was long and straight, made out of brass or silver, and could be up to 6ft long. The instrument was known for its loud and clear sound, which could be heard from a great distance.
Thank god Douglas Levison wasn’t around in medieval times!
