A young pianist realizes that mistakes can sometimes lead to joyful discoveries

When Hannah plays piano, music dances in the air. Her notes line up and hold hands, stand straight and spin. They keep perfect pitch and a steady tempo. And Hannah, elegant and serious, dreams of becoming a famous musician.

For her school concert, Hannah chooses an ambitious piece and vows not to play a single wrong note. But no matter how diligently she practices, a wrong note sneaks into her music--including on the day of the performance. Ashamed and upset at the imperfection, Hannah sulks ... until she sees her little sister, Jenny, lovingly dance and play with the wrong note, eventually inspiring Hannah to toss out her sheet music and improvise something completely new. And Hannah likes the sound! The notes aren't perfect, but they are perfectly hers.

Playful phrasing is paired with lively, expressive illustrations that give true character to the music notes in this pitch-perfect story about creative expression.
