Music schools are specific educational institutions which teach children to understand musical language, the rules of musical writing and how to play an instrument. It is assumed that children who enroll in music school have a certain level of "musicality," i.e. possess musical ability. Starting from this premise, in this paper we wanted to identify the number of musically gifted children, from the total number of children enrolled in the first year of lower music school. The research was conducted on 125 learners who enrolled the first year of Music school Josif Marinkovic in 2014/2015. The paper was organized as a linear study which followed the achievement of learners during the aforementioned school year. The study was conducted by solfeggio and musical instrument teachers. The identification of musical giftedness was followed through the following criteria: recognition and reproduction of tones and intervals, reproduction of rhythmic models and reproduction of short music units. Solfeggio teachers monitored the first two criteria (recognition and reproduction of tones and intervals and reproduction of rhythmic models) while musical instrument teachers monitored the other two (reproduction of melody phrases and reproduction of short music units. Achievements were assessed four times during the school year and a comparison of results gathered by solfeggio and musical instrument teacher was conducted. At the end of the school year a result analysis was conducted; the results of which showed that 13 learners who were monitored by solfeggio teachers and 9 learners who were monitored by music instrument teachers successfully completed the criteria. Methods for evaluating the proposed criteria and analysis of the gathered results will be presented in this paper. (A bibliography is included.)
