relationship between vocal pitch-matching and learning disabilities

Pitch-matching tests were conducted with learning disabled (LD) and non-learning disabled (NLD) third through fifth graders to examine whether a significant difference between pitch-matching abilities exists. Subjects were given a two part pitch-matching test using a tape recorded vocal model. The vocal model was a 12 year-old boy with unchanged voice singing the test examples on the neutral syllable "loo." Subjects were instructed to echo the vocal model and were given a single point for each correctly sung pitch. Statistical analysis revealed a significant difference in the pitch-matching skills of the learning disabled and the non-learning disabled students.
