Emotional messages do not easily reach to the tone deaf people unless they are catching the right facial expressions or body language of the speaker, says a new study, which implies that the earlier thought different parts of the brain behind the functioning and controlling of the music and language abilities, could be more closely related as were thought.

The latest findings of the experts have highlighted about the often failure of the tone deaf people in hearing the emotional messages like sadness or annoyance from the speaker's speech, especially until they read the right facial clues or body language of the speaker.

"Music and language were thought to be completely separate but it turns out that music and language share an evolutionary history", said lead author of the study, Mr. Bill Thompson, a music and brain expert from the ARC Centre for Cognition and its Disorders at Macquarie University.

The above study and its findings have been published today in the Proceedings for the National Academy of Sciences.

Researchers played recorded phrases to a controlled group of 12 people along with another group of 12 people suffering from congenital amusia or tone deafness. The content of the recorded phrases was neutral but read in a variety of different vocal tones hinting annoyance, sadness, tenderness or other emotional states. They noticed the tone deaf participants to be failing at detecting the emotional subtext in the phrases.
