Every note on Lily's old piano sounded like a grumpy frog. Its keys were stiff, and its strings hummed like a sad bee.

Outside her window, the birds sang a happy, bouncy song. Lily listened close, her head tilted.

She pressed a key. It was too low. She turned a tuning peg. Now it was too high.

A robin chirped a bright, clear note. Lily turned the peg just a little. The piano sang back the very same sound.

She tuned each key to a different bird—blue jay, sparrow, wren. The whole piano learned to sing like the morning.

Now Lily's piano played the music of the sky. Every time she touched the keys, the birds would chirp along.
