Excerpts from Rustom Mody's message of 2011-07-17 05:33:44 +0200:
I am preparing to give a talk on the wider
ramifications of music.
One of the things I wish to demonstrate is that things that look different
are merely analogs but at different scales.
eg if something vibrates at 400Hz we hear a sound of A-flat. If it
'vibrates' at 4 Hz we hear a beat.
In the same analogy a 2 vs 3 poly-rhythm (should?) change to a do-so chord.
And so on.
I suggest you do some experiments before you give a talk. At 4 Hz you
won't be able to hear anything, you won't even be able to reproduce a
4 Hz sound with common speakers.
Is there some kind of software where I can make a 4 Hz
beat and pull a
slider or a freq text box entry until it sound like a A-flat note?
puredata springs to mind, it's easy to use and has everything you need.
Regards,
Philipp
