Bruno Bjelinski was a Croatian composer and educator. His musical talent was perceived early in his childhood when he tried to write his first compositions, and later on he got formal education at the Academy of Music in Zagreb. His works are characterized by lively rhythms, original melody and a specific harmonic language, all of which gives his music a tone of modernity. Although Bjelinski does not belong to the musicians of the national musical direction, his works appoint to our country’s artist and educator. This is mostly present in his rhythmic, which is to a certain extent based on metric patterns of our southeastern folk music, and also in melody, influenced by the Mediterranean. When it comes to musical theater and education, Bjelinski achieved greatest success in the ballet Peter Pan. Having in mind stories for children, he did not pursue to create any special constructions, rather making the action realistic, thus approaching successfully to the mentality of young people. Being by nature witty and humorous, he used these traits in his work as well, creating humor on the account of his characters. Bjelinski composed numerous valuable works for children, including operas Maja the Bee, puppet shows The Ugly Duckling and The Jungle Book, as well as ballets Pinocchio and The Puss in Boots. Precisely these works, among others, show that Bjelinski was a great man who never stopped being a child, carrying child’s innocence and purity which he was able to transfer not only onto his family and sons, but also onto his students.
