Anatole and the Piano by Eve Titus illustrated by Paul Galdone*

Both my nine year old and seven year old enjoy the Anatole stories.
Anatole, the amazing mouse, loves music and conducts the Mouse Symphony Orchestra.  As much as he likes conducting, he longs to own a piano.  The only piano his size is on display in the Musee de la Musique. Some unusual circumstances pave the way for Anatole to own this piano.
Delightful!
*Highly recommend.
