Rosa's grandma is sick and must stay upstairs in bed. And so the big chair in the living room is often empty. And the money jar—in which the family saved their change to buy the big red chair and Rosa's accordion—is empty too. All extra money must be used to take care of Grandma.

After school Rosa and her friends Leora, Mae, and Jenny often make music for Grandma. She says their playing makes her feel like a girl again, dancing at a party. And that is the beginning of Rosa's wonderful idea.

A kaleidoscope of emotions—joy, sadness, merriment, and love—bursts from the pages of this exuberant book.
