This song was composed for the International KODOMO Choir Festival held during the World Symposium on Choral Music in Kyoto 2005. In 2006, the composer arranged this song into the mixed choir version for the joint concert in Singapore. A choir in Singapore, a choir from the Philippines, and the choir of Ko Matsushita himself from Japan were gathered. Through the work divided into three groups, our prayer for peace spreads like waves turning into whirlpools. This piece should be sung powerfully and brilliantly.
