ch as hers does, it was only a matter of time before it was Ava's turn to pick out an instrument. Her mother plays the piano, her father plays the violin, and one brother plays the cello while the other plays the clarinet. As soon as Ava selects an instrument, she will be able to join them as they practice for the annual holiday concert. And her family has definite ideas on what instrument Ava should select, from the piano to the flute to the violin. But Ava isn't interested in any of them. Ava wants to play the tuba. And she gets her wish. But playing the tuba isn't as easy as it seems. And there is no place for a tuba in the annual concert. But with the encouragement of her music teacher, Ava finds a place for her and her tuba in a special holiday celebration.
