I wrote this when my cat passed away, This is a song that conveys my gratitude and says that you will live forever in the sea of my heart. Although the structure is simple and the song is simple, I wanted someone to sing it as a choral song, so I made it into a sheet music. A=432Hz Just intonation is used at important points. In actual performance, please decide the Hz appropriately. The cello is optional as it consists of a piano and a three-part chorus.
