The Genetic Awesomeness of Perfect Pitch
This explains everything about my horrible singing. I have a genetic disadvantage! It’s not my fault! From The Daily Mail:
Perfect pitch may be part of the genetic programming of certain individuals, a study suggests.
Scientists believe nature as well as nurture can help gifted singers hit the right note.
People with perfect pitch have the ability to sing any note at precisely the right frequency without a reference tone to guide them.
Perfect, or absolute, pitch is extremely rare, but more common among speakers of tonal languages, such as Mandarin Chinese, who have musical training.
Although a link has been seen between learning music and perfect pitch, most people lack the ability even with musical training.
