[ABE-L] [Release] MusMat Journal Vol. V No. 1

[Hugo Carvalho]

The MusMat Research Group is very pleased to announce the release of the
first number of the fifth volume of MusMat • Brazilian Journal of Music and
Mathematics. This issue comprises seven exciting papers, that present the
results of original and innovative research in the field. The number opens
with a work by Robert Peck, where he applies the Power Group Enumeration
Theorem to extend the theory of beat-class sets by also considering rhythms
with more than one voice. Next, Gideon Effiong shows how quasigroups can be
used as a unifying framework to describe musical objects and events, such
as chord inversions, n-tone composition charts, and melodic motions. Ciro
Visconti then discusses how graph theory can be used to describe all
classes of trichords and tetrachords in Neo-Riemannian theory, expanding
beyond triads and seventh chords. Francisco Aragão presents an application
of Kripke Semantics to identify if a sequence of chords constitutes or not
a tonal progression, which can be used to create a software to benefit
students that do not have easy access to a harmony teacher. Subsequently, Juan
Sebastián Arias-Valero and Emilio Lluis-Puebla develop deep relations and
philosophical reflections between Gesture Theory and Category Theory.
Next, Silvio
Ferraz describes a series of patches in Max/MSP environment tailored to aid
musical analysis and composition and exemplifies it with the composition of
a piece based on Brahms Op. 119. The issue closes with Daniel Moreira
introducing
the concept of compositional entropy, which deals with the amount of
freedom of a composer when dealing with compositional choices, and such a
concept is demonstrated in musical texture.
