Many similarities between music and speech encourage observation of relationships between mechanisms of perception of the two phenomena. One of the ways of investigating them is to study patients afflicted with amusia related to difficulties in music reception and expression. Congenital amusia, the subject of the present article, is most often defined as a deficit in musical pitch perception. The latest research results suggest that it may also be related to auditory memory disorders, impairments in musical timbre perception, and their temporal organization. Because in speech prosody many items of information are encoded by means of changes in vocal pitch, temporal organization of prosodic features and timbre of voice, it is necessary to find out how perception disorders concomitant with amusia are related to the process of perception of prosodic structures. The article presents the results obtained in tests for music perception and speech prosody perception by three six-year-old amusic girls, which were compared with the results obtained by the control group consisting of 10 six-year-old children (five girls and five boys) The results obtained confirm the relationship between amusia and a reduced ability of speech prosody perception.
