This study investigated the relationship between expressive language ability and rhythm perception, pitch perception, vocal range, and vocal midpoint for 28 mentally retarded adults. A standardized speech test determined language scores, a standardized music test assessed rhythm and pitch perception, and vocalization determined vocal range and midpoint. Multiple correlation and multiple linear regression analyses indicated a significant correlation between expressive language ability and rhythm perception. Further research with music tests more appropriate for mentally retarded adults is recommended.
