Introduction:
The aim of music therapy offered in the World Hearing Center is to accelerate rehabilitation and auditory development of people, including children, with hearing implants. The purpose of therapeutic musical activities is to shape and improve the patient’s overall auditory and cognitive development.

Material and methods:
The study was conducted on 5 children, aged 8–11, who had undergone cochlear implant surgery. The group was tested before the start of music therapy classes and after 3 months of classes involving novel music compositions called ‘Instrumental Theatre’. The classes incorporated special Active Music Concerts (for participation) and Passive Music Concerts (for listening). Assessment were done with a questionnaire tool called Prima Volta.

Results:
The results indicate that music therapy had a significant effect on the development of auditory functions, especially sound identification and auditory memory. Observations made with Prima Volta indicate that the children were much more engaged with music.

Conclusions:
1. Scarce academic literature and very few clinical resources indicate the need for further development of original music compositions for use in music therapy for children with cochlear implants. 2. For a more comprehensive assessment, the Instrumental Theatre program needs to be continued and the results assessed after 6 and 12 months of therapy.
