[FRIAM] FW: Fractal discussion Landscape-bird songs

Fri Feb 17 02:19:37 EST 2017

Well, there's order, duration, frequency and a bunch of other stuff.
There is work from the signal analysis world, where people are concerned
with fractal structure in signals as a means of compression, and tho its
been years since I've done neural nets, I imagine heartbeats or nervous
system signaling would qualify.

As you remember, I am especially concerned with continuous
developmental/learning aspects, rather than specific adult organisms at a
specific time in some stable environment.  That said at my age I am of
course biased.

In my realm there is a figure-ground relationship at different scales
between the developing traditions, the drummers, the individuals in the
local group playing some arranged piece in the developing tradition, the
drum itself (driven amplifier dynamics), drum design (much beyond
membranophone descriptions and into wood types, metamaterials, turbulent
flow, variance in the thickness and biology of skins and stretching
processes, and such), the physics of the drum at the time it is played
(humidity, temperature, what's happening in the drum next to it, how
quickly it responds to that and the individual strike, the shape, mass,
elasticity and internal qualities of the drumsticks, a large number of
physiological qualities of the individual drummer and how each drummer
works with focus, efficiency of motion and process,  the acoustic
environment of the venue, the many ways in which the audience or a
particular kind of audience responds and in which you can evoke or respond
to those qualities.  So a complex drumbeat to me might not necessarily mean
a sequence of beats, but rather a single beat in which all those qualities
come together coherently (to me or anyone present now or in history) in a
single hit.   Even if the state space of the aforementioned qualities is
not precisely knowable just now.

I don't imagine this is particularly different for any musician or that it
necessarily qualifies as complex as you might mean it.   I'm certainly
willing for that bar to be high.  As some say, you are the instrument, the
voyage makes the captain, etc.

Tying back to "temporal fracticality", the notion of temporal direction can
maybe get factored out (a la Tralfamidorians) , ie many birds through their
song are trying to get laid (temporal pun intended).   The eaglet is the
father of the eagle, neh?. We make assumptions about how birds experience
time.   There seems to be a "temporal emergent locality" that defines the
horizons of temporal self-similarity (there's a lot of "emergent locality"
stuff in the physics literature - not sure it applies here).
