This is the first work in the "River" series, born from Sasaki's idea that "music was born on the banks of the river." The lives of people living on the banks of the river are depicted through "sounds" such as the bells and violins that ring through the town. The story is set in Cremona, a town on the banks of the Po River in northern Italy. A-san, a tuner, deepens her ties with the people living in the Po River basin while repairing broken violins.
