Cavalry and Infantry Standards
The flag with the Persian coat of arms," noted N. N. Murav’ev in his notes (1817), "stands in the middle of the battalion with the musicians dressed in yellow jackets. These musicians consist of drummers, fifers, and trumpeters. The first beat the drum well, but the second, who have not the least natural talent for music or any understanding of rhythm, play so that it is only with difficulty that one can recognize it is ‘God Save the King’ that they are tooting." In the same year, Yermolov wrote, "Drummers and fifers are dressed in either red or yellow coats, with lace on the seams and arms, white cords on their caps, with a tassel hanging over the right shoulder." In later years the uniforms of musicians remained just as colorful.
