Composing with Overtones!
This is an interesting video.
Liam Carey says:
This is a short primer on spectralism that I made for my students. It focuses on the French/German schools of spectralism (sorry Romania) and features the music of Gérard Grisey, Tristan Murial, Kaija Saariaho, and Georg Friedrich Haas.
Well, let's see if I've got this right...
We know a note sounds differently on different instruments, and we know the same note sounds differently played in more than one position on our fingerboard. That difference comes from 'overtones' - the note and it's overtone frequencies produce the 'timbre' of a note - and there's 'harmony' within the timbre.
Now, try composing with that. (lol)
... and I thought Atonal music was crazy.
