Sylvain Auroux: La sémiotique des encyclopédistes (1979)
Three encyclopedic caracteristics of general validity:
unité (unity) grammar of synthetic discourse philosophy
intégralité (completeness) all facts dictionary
discours (discourse) encyclopedic ordering representation
euchar
hostiae

3. ramification type ~ completeness
reference ~ unity
linear ordering ~ discourse

4. concepts are points in concept spaces
(Kritik der reinen Vernunft, B 324) Man kann einen jeden Begriff, einen jeden Titel, darunter viele Erkenntnisse gehören, einen logischen Ort nennen. You may call any concept, any title (topic) comprising multiple knowledge, a logical site.
Immanuel Kant
concepts are points in concept spaces

6. Simple Forms = Elementary Spaces

7. Simple 1
<form_name><type>(coordinator)
example:
‘Loudness’
A = STRG = set of strings (words) from a given alphabet
Simple

11. <form_name><type>(coordinator)
Simple +
<form_name><type>(coordinator)
<denotator_name><form_name>(coordinates)
Simple
example:
‘Eulerspace’
Extend to more general mathematical spaces M!
example:
‘myEulerpoint’
point in M
e.g. Euler pitch spaces....
octave
fifth
third

12. <form_name><type>(coordinator)
A module M over a ring R (e.g., a real vector space)
Simple
Examples:
M = —3 space for space music description
M = –3 pitch space o.log(2) + f.log(3) + t.log(5)
M = Ÿ12, Ÿ3, Ÿ4 for pitch classes
M = Ÿ Ÿ365  Ÿ24  Ÿ60  Ÿ60  Ÿ28 (y:d:h:m:s:fr) for time
M = ¬, Polynomials R[X] etc. for sound, analysis, etc.
<PitchClass><Simple>(Ÿ12)

13. Compound Forms = Recursive Spaces

14. spaces/forms exist three compound space types: product/limit
union/colimit
collections/powersets

15. Limit <form_name><type>(coordinator)
example:
‘Note’
sequence F1, F2,... Fn of n forms
Limit
<denotator_name><form_name>(coordinates)
example:
‘myNote’
n denotators from F1, F1,... Fn
example (n=2):
(‘myOnset’,’thisPitch’)

16. Limit K-nets (networks!) <form_name><type>(coordinator) F1
<denotator_name><form_name>(coordinates)
Limit
extend to diagram of
n forms + functions F1 Fn Fi
example:
‘Interval’
K-nets (networks!)
example:
‘myInterval’
n denotators, plus arrow conditions
example:
(‘note1’,’on’,’note2’)
Note Onset Note

19. Colimit <form_name><type>(coordinator)
example:
‘Orchestra’
sequence F1, F2,... Fn of n forms
Colimit
<denotator_name><form_name>(coordinates)
example:
‘mySelection’
one denotator for i-th form Fi
example:
Select a note from celesta

20. Powerset Power 1 <form_name><type>(coordinator) one form F
Example:
‘Motif’
one form F
Powerset
<denotator_name><form_name>(coordinates)
A set of
denotators
of form F
example:
{n1,n2,n3,n4,n5}
F = Note
example:
‘thisMotif’

21. Powerset Power 2 <form_name><type>(coordinator) one form F
Example:
‘Chord’
one form F
Powerset
<denotator_name><form_name>(coordinates)
A set of
denotators
of form F
example:
{p1,p2,p3}
F = PitchClass
example:
‘thisChord’

22. Gluing together spaces of musical objects!
<form_name><type>(coordinator)
Colimit
diagram of
n forms F1 Fn Fi
Idea: take union of all Fi and identify corresponding points under the given maps.
Gluing together spaces
of musical objects!

23. Colimit <form_name><type>(coordinator) F1 Tn D = Chord FnFi
Chord
D = Tn
Tn{c1,c2,...,ck} = {n+c1, n+c2,..., n+ck} mod 12 (transposition by n semitones)
Result = set of n-transposition chord classes!
BTW: What would the Limit of D be?

32. The denoteX notation for forms and denotators

33. Name:.TYPE(Coordinator);
Forms
Name:.TYPE(Coordinator);
Name = word (string)
TYPE = one of the following: - Simple - Limit - Colimit - Powerset
Coordinator = one of the following: - TYPE = Simple: STRING, Boole, Ÿ, — - TYPE = Limit, Colimit: A sequence F1,... Fn of form names - TYPE = Powerset: One form name F

34. Name:@FORM(Coordinates);
2. Denotators
Name = word (string)
FORM = name of a defined form
Coordinates = x, which looks as follows: - FORM:.Simple(F), then x is an element of F (STRING, Boole, Ÿ, —)
- FORM:.Powerset(F), then x = {x1, x2, x3,... xk} xi = F-denotators, only names xi:
- FORM:.Limit(F1,... Fn), then x = (x1, x2, x3,... xn) xi = Fi-denotators, i = 1,...n
- FORM:.Colimit(F1,... Fn), then x = denotator of one Fi (i>x, only names x:)
