Recent musical explorations have revolved around the concept of Spectralism. In researching and exploring spectralism, I came across this article from the London Times Online. It asks the question is Spectralism the future of classical music?
"Before devising each piece of music, a composer would feed a computer a note, say the sound of a bell or a violin, and a programme would unravel it, revealing a spectrum of pitches, showing up as coloured lines on a graph. The composer would then take each of these pitches and get each part of the orchestra to reconstitute the original sound".
