Über dieses Buch

This is the fourth volume of the second edition of the now classic book “The Topos of Music”. The author presents appendices with background material on sound and auditory physiology; mathematical basics such as sets, relations, transformations, algebraic geometry, and categories; complements in physics, including a discussion on string theory; and tables with chord classes and modulation steps.

Appendix: Sound

Frontmatter
A. Common Parameter Spaces
Abstract
This appendix chapter is an overview, not an exhaustive treatise of spaces which parametrize sound objects. These spaces where sounds are positioned always define an aspect, never the totality of music thinking, and every attempt to define a preferred space will narrow the music thinking, not the music. The best that can occur is that we offer an encompassing or at least a representative ensemble of parameter spaces which are interrelated by a precise relation. To this end, it is recommended to distinguish topographic positions, above all in their realities and communicative perspectives. This will also entail the corresponding mathematics.

B. Auditory Physiology and Psychology
Abstract
“Music listening” is a metonymy of understanding music: For all participants, the ear functions as an interface for perceiving music between physical, psychological, and mathematical reality. But a metonymy is not the matter as such. This is what deaf Beethoven teaches us impressively: his innermost ear was an organ of imagination that was uncoupled from the material ear. And the physiology of the hearing process teaches us that the neural coupling of the ear to the respective cortical regions is extremely complex and still hardly understood. Section B.1 is written to give an overview on auditory physiology.

C. Sets, Relations, Monoids, Groups
Abstract
The language of sets describes mathematical facts in a classical way. An alternative foundation to sets is the language of categories, see Appendix G.

D. Rings and Algebras
Abstract
A (unitary) ring is a triple (R, α, μ) where (R, α) is an abelian group whose operation α is written additively (α(r, s) = r + s) with neutral element 0 R , and (R, μ) is monoid, written multiplicatively \( ({\mu}(r, s) = {r}\cdot{s})\) with multiplicative neutral element 1 R such that these operations are coupled by distributivity, i.e., \( (r + s) \cdot {t} = {r} \cdot {t}+{s} \cdot {t}, {t} \cdot (r + s) = {t} \cdot {r} + {t} \cdot {s}\) for all \( {r, s, t} \ {\in} \ {R}\).

E. Modules, Linear, and Affine Transformations
Abstract
Let R be a ring, then a (left) R-module is a triple (R, M, μ : R × MM) where M is an additively written abelian group and μ is the scalar multiplication, usually written as μ(r, m) = r.m if μ is clear (R is also called the ring of scalars, and M the group of vectors), with the properties:

F. Algebraic Geometry
Abstract
Given a topological space X, its system of open sets Open X is viewed as a category with inclusions as morphisms.

Appendix: Tables

L. Euler’s Gradus Function
Abstract
This table lists the rational numbers x/y with Euler’s gradus suavitatis \({\it \Gamma (x/y)}\leq\;10, \mathrm{see \; also}\; [161]\).

M. Just and Well-Tempered Tuning
Summary
This table lists the just coordinates of the just tuning intervals (with respect to c, second tone in first column) according to Vogel [1089], see Section 7.2.1.4, together with the value in Cents, and the deviation in % from the tempered tuning with 100, 200, 300, etc. Cents.

N. Chord and Third Chain Classes
Summary
This section contains the list of all isomorphism classes of zero-addressed chords in PiMod12. The meanings of the column items are explained in Section 11.3.7.

O. Two, Three, and Four Tone Motif Classes
Summary
The order of these representatives is a historical one.

P. Well-Tempered and Just Modulation Steps
Summary
In the following table, the exclamation sign (!) in column 6 means that quantization is not possible for every translation quantity p in the notation of Theorem 30.

Q. Counterpoint Steps
Summary
All the following tables relate to representatives of strong dichotomies (X/Y) which are indicated in the table after the counterpoint theorem 33 in Section 31.3.3.
