This is a valuable SA♭-tuned Tsuchigokoro Ocarina, selected by professional musician Masahiro Miyamura. The SA♭ tuning is the same as the one favored by Sojiro. It has a higher pitch than the SC tuning, yet produces a clear, bright tone that is not harsh on the ears. It can also be used for solo performances. The sound of the Tsuchigokoro Ocarina is truly unique, so please take this opportunity to enjoy it.
