According to Bujas Petković and Frey Škrinjar4, autism is a pervasive developmental disorder beginning in childhood, lasting a lifetime and overtaking most psychical functions. The affected children’s interest in music, positive reactions and frequency of highly developed musical hearing pave the way for therapeutic methods which can help them develop social competences and join their peers’ activities. Music is a unique asset in handling neurological problems because it engages most areas of the brain (Hurt-Thaut, 2016).5 Therapies based on music foster brain neuroplasticity by strengthening connections which compensate for disadvantages in the damaged brain parts. Listening to music improves memory and coordination and can develop additional skills, including speech and motor functions (Tomatis, Ferguson, & Campbell, 1992).6 This MA thesis aims to compare different approaches to music therapy of children with autistic spectrum disorders (ASD) in Croatia and to examine their cognitive, motor, social, communication and emotional progress. Various individual and group therapy programs for children aged 3 and older are conducted in Croatia. The best results are achieved by the age of 7. In spite of using different methods and approaches, most interviewed therapists quote similar positive outcomes of music therapy of children with ASD. Side effects are scarce and short-lived, whereas improvements are generally permanent if therapy is conducted during the preoperational developmental stage. Due to the spreading availability of therapeutic practices in Croatia, as well as increasing awareness of the benefits of music therapy, this work can serve as a starting point for further research of therapeutic methods which can help children with ASD, especially in the field of communication, cognitive and social skills.
