...After realizing that I haven't changed my post since 2007, here's a new news post with no real purpose.

Although I don't think they gave an exact answer to WHY some people can't sing in tune.
I've a friend who sings like... 3 semitones off =_=;; and I try to understand why she is so off tune and why she can't tell that she's so off tune haha.

And here are a few more scientific articles about music skills:

End of pointless news post ¬_¬;;;
