Music computer technologies (MCT) open up wide opportunities for blind students to more effectively study the diverse content and methods of presentation of educational material in Informatics, contributing to the achievement of positive learning outcomes in a shorter time. This is especially important for children who study in children’s music schools. Mastering of MCT by children with profound visual impairment has a number of characteristic features, which are most clearly manifested in the initial period of studying Informatics. With the help of contemporary computer technologies (speech synthesizers, Braille displays, etc.), as well as due to the possibility of using “hot keys” blind students quickly master many MCT-programs.
