Peter is 12 and lives in Innsbruck, Austria. He’s learning the violin but at the moment it’s being repaired. But the music keeps on playing; he has to concentrate on choir practice, as the choir is preparing to sing in a church for Easter. It’s a very important time for him and his family. A trip to visit his sister – who’s doing work experience at the zoo – gives Peter the chance to discover the many different species of animals that used to abound in the mountains of Austria. Peter heads off to Salzburg to pick up his violin from the stringed instrument maker. It’s the perfect opportunity to visit the childhood home of Peter’s favorite musician: Mozart.
