There’s really much, much more to this video by Charles Limb than the couple of points I’m about to select but here goes….

There is a very clear depiction, at 06:15, of the difference of range of frequencies (Hz) and level (dB) in music and language.

There is also an interesting demonstration, at 07:07, of how those of us with normal hearing take pitch perception for granted – compared to cochlear implant patients, whose perception can be out by as much as two octaves[kml_flashembed movie="http://www.youtube.com/v/bTE0MRRXNzs?rel=0" width="425" height="350" wmode="transparent" /]

There is also a very interesting talk on neuroscience and musical improvisation by the same author here – look out for great demo of piano improvisation by Keith Jarret at 01:15 – including some nice ‘outside playing‘ at 02:08 [kml_flashembed movie="http://www.youtube.com/v/BomNG5N_E_0?rel=0" width="425" height="350" wmode="transparent" /]
