I recently saw a post that claims to test your ability to recognize tones of different music and gives you a grade at the end of the test.
I thought it might be fun so I added it to my webpage if your interested.
It claims to be scientific.
Your input would be interesting
Enjoy. (About 1/2 way down my homepage for the link)
PS If anyone has a problem that I listed my homepage here let me know and I will modify the post.
