The perception of pitch contours in typically developing children with and without musical training

Perception of pitch contours

Abstract

Background and Aim: Musical training causes neuroplasticity changes which are transferred to other modalities like- audition, cognition. All the musical tests uses musical stimulus, thus making it hard for the children without musical training due to the unfamiliarity of the stimulus. Dynamic stimulus like pitch contour, mimics musical stimulus. Hence the present study aimed to investigate the  perception of pitch contour for different tonal stimuli in typically developing children with and without musical training.
Methods: Children aged  9-13 years  were categorized into two groups: group-I with formal musical training and group-II without musical training. Musical abilities were assessed using the Montreal Battery for Evaluation of Music Abilities (MBEMA) test with melody, rhythm, and memory subtests. The melody and rhythm subtests had discrimination of musical tones, while the memory subtest had identification of familiar melodies from previous subtests. The pitch contours for tonal stimulus were generated using PRAAT software . The pitch contour consisted of tones sweeps representing nine patterns (rising, rising-flat,rising-falling, flat, flat-rising, flat-falling, falling, falling-flat, and falling-rising) for 500Hz, 1kHz, and 2kHz tones. Children were familiarized with these contours and then tested using closed-set identification task  using DMDX software
Results: Group I performed better than group-II in both musical ability and pitch contour identification tests. MANOVA revealed significant differences in MBEMA  and  pitch contour identification between the groups.
Conclusion: The contour perception of the different pitch shows evident differences induced by musical training. It is proposed to assess the musical ability of the individual with the tonal pitch contours.
