Imperial tombs and funeral music were under the jurisdiction of Shoryoshi (Mausolea Office) (Shoryoryo [Bureau of Mausolea]) and Kosuishi (Drums and Fifes Office) respectively, and there was significant crossover between work of Sogishi and that of them, so sogishi was absorbed into Kosuishi in 808.
陵墓は諸陵司(諸陵寮)・送葬音楽は鼓吹司の管轄であったため重なる部分が多く､808年に鼓吹司に併合された。
