Brain waves can create music, claim boffins after Pink Floyd demo
SONGS can be created using people’s brain waves instead of sheet music, boffins reckon.
They recreated Pink Floyd’s 1979 hit Another Brick in the Wall using electrical activity recorded from people listening to the real thing.
Thousands of electrodes stuck to the heads of 29 patients created a map of how the brain reacted to specific notes in the tune.
This was then turned into a spectrogram — a type of graph that shows sound waves — and read by a computer to turn it back into a melody.
The result was the distorted but recognisable tune of the chorus to the classic track composed by Roger Waters.
US scientists hope the work may lead to more natural computer voices for people who cannot speak.

Prof Robert Knight said: “It gives a way to add musicality to brain implants.”
Brick In The Wall topped the charts in the UK and US and sold over four million copies.
