Here's a link to a demonstration of what some researchers have managed to create in sound by way of converting human brainwaves to MIDI notes on a piano.

I notice that all phrases seem to end on a lower note, the lowest note in the phrase, even. Could this be evidence of the functional equivalent of the Stop Bit? Not narly enough of a data sample set to jump to conlcuisons here.

The musical phrases, however, I find, well, "musical" sounding in nature, some of the 20th century neoclassical composers may have been tapping into the same structures somehow.
