I found this great post over at NoiseAddicts.com.
Mari Kimura is a New York-based violinist who is able to play notes that are out of the range of her instrument. (Sound files of these phantom notes can be found here.) Scientists are working to figure out how this is even possible, and some responses over at the NA post claim to have the answer. But the brilliant aspect is the fact that a musician somehow broke free from centuries-old limitations. As Ms. Kimura humbly suggests:
“As an artist you are always searching for ways to expand the sound.”
