Re: About silence and breath

Responding as a composer, not a scientist, in this context I have used the word "segmentation" to mean to determine where something 'begins' and 'ends', possibly a very low level (fundamental) process, and this (in my use) is perceptual. Segmentation therefor occurs at many levels, largely dependent upon the perceptual / cognitive processes of the individual.

'Silence' in music (as noted by others) may be a perceptual phenomena, and not related to having 'no acoustical event'. The Mahler First Symphony begins from 'silence', and the silence is sustained (sic) behind the acoustical events of the introduction. As a perceptual event, I consider acoustical silence an implausibility. If you wish to model silence acoustically, it looks like this 00000000000, however if you wish to model silence in a 'musical' sense, you may wish to research [what I consider to be] the first step in auditory scene analysis, segmentation.

When you say segmentation you are refering to something like the grouping structure of Lerdhal and Jackendoff?
Please keep us informed on your progress.
Of course amigo!

Subject: About Silence

Hello everyone!

My name is Pablo. I apologize in advance of my english =D.

I recently joined this mailing list because I'm doing some research
about music. My intention is to use computational/statistical models to create music, and that models be driven by cognitive/musical claims (1).

Since the very beginning of my research I had trouble modeling silence. The silence is not just another pitch which has the ability of not to sound. I think that silence has to be treated apart from pitches, but I
don't know how.

So here comes my question: Do you know anything I can read to help me
out with this?

Thanks you all!


(1) If you are interested, you can hear an example here of what I've
already done: http://lafhis.dc.uba.ar/%7Epzivic/E.nar.mid

In that example, the piano is of Scott Joplin, and the solo is composed by mi program. The silences that you hear, are artificial, is just a simple rule that I
introduced, if the solo plays all the time it gets annoying.
