ToWAMoFM/01/01 Energy/03 Accumulation of Corpuscules
Description
- In Granular Synthesis the grains are beyond the threshold of auditory perception
- This energy model functions through accumulation; it's about the Process not about a Form
The "Image-Model" of a sound
- Depending on the scale of perception, the same sound source can be corpuscular or a flow:
- The sea (close = corpuscle-like froth, far off = flow), with water in general it's the same idea
- A crowd on a football field (from far away = corpuscles, those close to you = detailed events, shouts, etc.)
- Wind in leaves (close = corpuscles, far = flow)
- We hear something global in the whole collection of grains
- We can hear the mini-particles that stand out from the whole (for example, those generated by aluminum foil) by focusing on the high frequencies
Aspects
- Grain
- Mass
- Pitch
- Caliber - size from large to very small
- Density of accumulations are factors of perceptual variations in the accumulation of corpuscles.
- Think of the "noise" current in electronic signals as well
Commentary
- There's a difference between Friction and accumulation of corpuscles
- If Friction generates individual or iterative grains, or if the grain is so fine that it approaches a smoothness of sound, then accumulation of corpuscles refers to when the perception focuses on more of a gestalt Person/Pierre Schaeffer/Form Matter Pair than on the detail of the granulations.
- The Mass of the grains is a part of the sound here as well; there is a viscosity, a density to the grains.
