A musical troupe brought together through the use of Cornelio's DoReMi Rune. The symphony’s membership included five DoReMi elves, FaSoLa, LaTiDo, MiFaSo, ReMiFa, and SoLaTi. However, the Orchestra was scattered in SY 449 by Prince Freyjadour Falenas, who came upon the troupe and was attacked by the elves. Cornelio insisted on accompanying Freyjadour in his travels in order to find the now-scattered elves. He proved successful in this endeavour, and the DoReMi Elf Symphony Orchestra would provide music for the Loyalist Army during the Falenan Civil War.
Following the reunification of the DoReMi Elf Symphony Orchestra, Cornelio planned on expanding the orchestra to at least 50 DoReMi Elves.
