Deficits of music functions also known as amusia may result from one or more brain damage. Studies report that despite the musical system and language work of independent ways, some functions are used the same neural substrates. Thus language deficits as a result of brain damage may be associated with deficits of one or more musical functions. Currently the best tool to measure the deficits of musical functions is the Montreal Battery of Evaluation of Amusia (MBEA), a battery of 6 tests that evaluates the music processing on the discrimination of melodic organization (outline, scale, range), temporal (rhythm , metric) and incidental memory. In 2010, the test battery was translated and validated in Brazil by Marilia Silva et al and in 2012 was held the reduced version to better applicability. This study aimed to apply the reduced version of MBEA into two groups: aphasic expression (n = 5) and dysarthria (n = 6). There was no significant difference in the number of correct answers of the two groups in each test, but both had an average of less hits in metric test in comparison with other tests including the pace test, in common with speech..
