on the parade field, when troops passed in review, and in various ceremonies including ominous drum rolls accompanying disciplinary punishments. Children also served as drummer boys well into the nineteenth century, though less commonly than is popularly assumed; due to the nature of the job, experienced older men were preferred. In modern times, drummers are not employed in battle, but their ceremonial duties continue. Typically buglers and drummers mass under a sergeant-drummer and during marches alternately perform with the regiment or battalion ensembles. Military-based musical percussion traditions were not limited exclusively to the western world. When Emir Osman I was appointed commander of the Turkish army on the Byzantine border in the late 13th century, he was symbolically installed via a handover of musical instruments by the Seldjuk sultan. In the Ottoman Empire, the size of a military band reflected the rank of its commander in chief: the largest band was reserved for the Sultan (viz. his Grand Vizier when taking the field). It included various percussion instruments, often adopted in European military music (as 'Janissary music'). The pitched bass drum is still known in some languages as the Turkish Drum. Military drumming is the origin of Traditional grip as opposed to Matched grip of drumsticks. Parades The drumline is a type of marching ensemble descended from military drummers, and can be arranged as a performance of a drum, a group of drummers, or as a part of a larger marching band. Their uniforms will often have a military style and a fancy hat. In recent times, it is more common to see drummers in parades wearing costumes with an African, Asian, Latin, Native American, or tribal look and sound. Cultural drumming Various indigenous cultures use the drum to create a sense of unity with others especially during recreational events. The drum also helps in prayers and meditations.
