Autism is a complex neurological development disorder that affects the ability of verbal and nonverbal communication, behavior, complicates social interaction and occurs very early in the childhood. Although in human history this disorder existed much earlier, it began to be investigated and named only in the early 20th century. To this date, and in spite of numerous neurological and biological field studies that have resulted in only different assumptions, the cause of the disorder has not been revealed and its diagnosis relies on a group of symptoms that occur in children with autism. That group of symptoms is called an autistic spectrum, which helps us differentiate autism disorders from other developmental disorders. As part of various forms of treatment, mitigating the symptoms of autism and therapy, music therapy is increasingly used as auxiliary discipline. It uses music and its elements to influence the child's overall development and improvement of social and communication skills, and is performed with the help and supervision of a music therapist. The aim of the paper is to present the possibilities of music therapy and the ways in which it can positively affect children with autism in different areas of development. During the research of the topic and literary material, two models of music therapy have been found and presented with their features and approaches to meet the therapeutic demands of work with children with autism spectrum disorders. Those are NordoffRobbins and Alvin model. It has been shown that the mentioned models greatly help children with autism, especially in the communication field, offering them a possibility of better connection with their surroundings and consequently, improving their overall quality of life.
