Many questions remain in the field of amusia, and it can be challenging to make a correct diagnosis. This is due to the lack of gold standard research, formal diagnostic measures and public awareness. Isabelle Peretz of the University of Montreal has dedicated her laboratory to music and the brain. In 2003, the laboratory created a reliable and valid measure of amusia, called the Montreal Battery of Evaluation of Amusia. This test has 6 musical components, referred to as contour, interval, scale, rhythm, meter and memory tests. Since this test was published, Peretz has received frequent press and consequentially public awareness has increased. Hopefully increased public awareness will promote further research and interest in the field of amusia, and eventually lead to effective treatment of the disorder.
