this is the open space. you're on a highway, going up and downhill. you may take exits and go on overpasses. the contours of the traffic around you wax and wane like tidal cycles.
or, if you prefer, it's uncle braxy's ghost-trance for psy burnouts. the tiny vampire rave inside your skull outfit with circus midgets and wormholes.
spectral ranges are defined within the trance train. while the train accelerates you look at it through a telescope, while it decelerates you see every atomic gesture, every morpheme that makes it up.
the wavelets can be defined within slices of the spectrum, and restricted to discrete time/frequency relationships like scales and temperaments. they can range from long resonances to infinitesimally tiny crispers on transients, from faithful facsimile to clouds of resampled memory.
