Hey,

i'm going to sing at a small concert of our school next spring. i know that's still quite far away, but i have to ask other musicians for the accompaniment.

i'm looking for a sad song with japanese lyrics, i'm a soprano.
i already thought about "nemureru shiro" (rozen maiden souseiseki drama) and "you are my love" (tsubasa chronicle ost)

any ideas?

Uhh, off the top of my head. "Lilium" is a good song. Although the lyrics aren't japanese. It's from an anime though, haha. Sorry if this isn't of any help. But I think it fits being sad, and being for a soprano.
