What is a postspectralist music?

 Nobody really knows what it is. But:

  • [Sap] "the spectrum as a reference point, and not the main predominating element, when re-interpreted, functions as a declared aesthetic angle of the perception of a music sound", "the spectrum as a point of reference, however, an aspect not fully controlling the compositional process, as was typical of spectralists"
  • [Mor] "post-spectralism was opposed to serialism and spectralism, rejecting compositional dogma while still incorporating aspects of both styles into a freer approach"
  • [Mor] "a larger coalescence of institutional interests and resources aimed at solving a common problem; namely, the “psychoacoustic problem,” i.e., the difficulty of accounting for the enormous complexity of musical sounds in a computer programming environment."
  • [Mor] "liminal space between what is considered music and non-music"
  • [Mor] "a whole range of post-spectral compositional practices—i.e., those approaches to composition influenced by a frequency-based mode of thinking, a non-metric scaling of temporalities, an affinity for analysis and synthesis processes, and a commitment to the idea of composition as research into the physics of sound"
  • [Gas] "Post-spectral pieces use a method called spatialization of sound, in which electronic sounds or electronically manipulated sounds are perceived to be displaced to multiple spatial points, providing textural variety"

  • ? Add live play mode, where we only do midiOn, queue the notes, and then do simultaneous midiOff
  • ? Specify only curves of parameters, let the solvers find a solution, satisfying all constraints in dynamic

(draft) EPPDC, дизайн алгоритма

TODO: my notion page https://www.notion.so/PPDC-construction-50e4c555f0444468955b924c14c37013

PPDC: алгоритм

EPPDC: деконструкция алгоритма.

Какие есть важные моменты:

  • PPDC можно построить для любого связного графа, через итеративное добавление рёбер, причём рёбра можно добавлять в любом порядке, причём внутри алгоритма они добавляются ориентированно и есть 2 порядка добавления ориентированных рёбер, и можно выбрать любой из них.
Возможно, что в EPPDC в каждый пункт придётся внести изменения.

Мы будем исходить из гипотезы, что для любого связного графа можно также построить и EPPDC.

Какие возможны изменения по сравнению с PPDC:
  • С практической точки зрения, если мы хотим перебрать как можно больше графов, PPDC можно строить начиная с дерева и заканчивая полным графом, добавляя рёбра по одному, в случайном порядке. Возможно, что для EPPDC такая схема не подходит, и придётся каждый раз фиксировать граф который мы хотим построить, и мб наилучший порядок добавления рёбер.
    • Но это всё очень сильно усложняет схему алгоритма, например, непонятно, как выбрать хороший порядок добавления рёбер. Поэтому временно мы не будем рассматривать модификации в алгоритме, будем считать, что EPPDC можно построить при любом порядке выбора рёбер.
    • Ещё возможный нюанс - это выбор порядка ориентирования ребра. Если ребро (a,b), то либо мы добавляем сначала (a,b), потом (b,a); либо сначала (b,a), а потом (a,b). Кажется, что в идеале было бы хорошо, если б мы могли добавить ребро в любом порядке
  • Дальше мы пытаемся добавить неориентированное ребро (a,b). Сначала добавляем a-->b, потом b-->a
    • Добавление ребра a-->b означает, что мы хотим удлинить какой-то из путей, который заканчивается в a, до пути, который заканчивается в b
    • При добавлении ребра a-->b в каждой вершине начинается и заканчивается по 2 пути
    • При добавлении ребра b-->a в вершине b находится 3 конца путей, а в вершине a только 1
    • ...

Semiotics

Imaginary courses notes.


Wikipedia - https://en.wikipedia.org/wiki/Semiotics

Barthes' school of thinking (focused on the description of explicit signs taken in isolation)

Greimas' structural semiotics (where a sign has meaning only when it is interpreted as part of a system)


Wikipedia - https://en.wikipedia.org/wiki/Communication

Steps of plant communication: sender --emission--> cue --perception--> receiver --processing--> response


https://biosemiosis.blogspot.com/2008/07/macro-vs-microsemiosis.html

"1) Signs divide into formal and physical signs.

2) Physical signs divide into macro and micro signs.

3) The study of formal signs ==> 'Metaphysical semiotics'.

The study of macrosigns ==> 'Macrosemiotics'.

The studyo of microsigns ==> 'Microsemiotics'.

Scheme 1. A suggested trichotomization of the field of semiotics based on i) the
materiality and ii) the size of signs.


i) By 'Metaphysical' semiotics (or semiotic metaphysics?), I mean the study of signs on the most abstract and general level, or the metaphysics of signs (in contrast to the physics of signs). Pansemiotics, and triadic metaphysics of Peirce would belong to this branch of semotics.

ii) 'Macrosemiotics' is the study of macroscopic signs (e.g., words, sentences, pictures, sculptures, sounds, etc. ) that are visible, audible, tactile, and tastable to humans and other animals. Linguistics, literary art, visual arts, musicology, archtecture, dance, anthroposemiotics, and zoosemiotics would belong here.

iii) 'Microsemiotics' can be defined as the study of signs on the microscopic level (e.g., DNA, RNA, proteins, pheromones, cells). Biosemiotics of cells and their higher-order structures (e.g., organs, including the brain) analyzed in terms of molecules as the basic building blocks would constitute the main component of this branch of semiotics. Jesper Hoffmeyers work over the years and Macello's recent review article, among ohers, have laid the foundations for the field of microsemiotics."

The Biosemiotic Approach in Biology : Theoretical Bases and Applied Models 

"Also, from the 1960s to the 1990s, the semiotic approach in biology was developed in various branches:

  • Zoosemiotics, the semiotics of animal behavior and communication
  • Cellular and molecular semiotics, the study of organic codes and protolinguistic features of cellular processes 
  • Phytosemiotics, or sign processes in plant life 
  • Endosemiotics, or sign processes in the organism ’ s body 
  • Semiotics in neurobiology 
  • Origins of semiosis and semiotic thresholds
