It was the Turks who early on discovered the power of military bands to excite fighters while encouraging their warrior spirit, and to maintain discipline in unity during marches in times of peace. While the roots of this tradition reach back to the Hun Empire, Turks used music on the military field in an active and functional way. In particular, the morale of the army was boosted by the incessant beating of the large drum, "kos" (a large kettle drum) and by playing inarches.
