Complex and multiphonic voice signals of vocal improvisors are analyzed within the framework of nonlinear dynamics. Evidence is given that nonlinear phenomena are extensively used by performers associated with contemporary music. Narrow-band spectrograms of complex vocalizations are used to visualize the appearance of nonlinear phenomena (spectral bifurcation diagrams). Possible production mechani

Unlike what is usually taken for granted in semiotics, communication, in the sense of semiosis, does not essentially depend on transport and/or recoding. Instead, it consists in the creation of an artefact, with the additional setting of a task of interpretation. This task may be set by the addressee, just as likely as by the addresser. In making this suggestion, we are inspired by Husserlean phenUnlike what is usually taken for granted in semiotics, communication, in the sense of semiosis, does not essentially depend on transport and/or recoding.

Nonlinear phenomena have been reported in many diverse disciplines, including physics, health sciences, engineering, literature, neurology, geology and music. As this paper will show, nonlinear phenomena have robust potential for both performance and composition. It has been shown that nonlinear phenomena occur in the sound production of extra-normal extended techniques for both voices and musical

Thanks to Bruno Galantucci, “experimental semiotics” is usually nowadays taken to mean the study of “novel forms of communication which people develop when they cannot use pre-established communication systems”. In spite of Galantucci’s claim to have picked the label because it was free, it has actually been used in different ways at least twice before: by Colin Ware, who takes it to be involved w

Starting out from classical metaphor theory, I consider two models, the Overlap model and the Tension model-the difference between which may not have been spelled out in that tradition. Although the latter has an Aristotelian pedigree, it may be less generally valid than the Overlap model, at least if the requirement for tension is placed very high. The metaphors distinguished by Lakoff and Johnso

This 1 sonata uses simple generative principles, to develop networks of relatively high complexity in which intuition actively participates to produce an output with a certain degree of activity and acoustic nonlinearity.Albert-László Barabási, from the introduction to his book titled Linked: the new science of networks, “Just as diverse humans share skeletons that are almost indistinguishable,

This paper will discuss multiple sound sources of the vocal tract, focusing specifically on one type of multiple sound source, that of (imitated Tibetan) chant. First I will present a physiological outline of multiple sound sources, in order to better understand chant as just one of the many types of multiple sound sources that composers and performers might utilize. The main body of the paper wil

Palatal Sound is a model of vocal tract articulation influenced by physiologic and acoustic analysis of the voice. Specifically, the term articulation refers to all movement within the vocal tract that results in open, filter-like sonorities, as well as in turbulent to absolute airflow modification. This model presents a complete mapping of place within the vocal tract that features flexibility ac

The article is devoted to legal acts on combating corruption. The author gives a classification and review of these legal acts. The article analyzes not only legal acts specifically aimed at preventing corruption, but also other legal acts and a wide range of measures that create the necessary conditions and a favorable environment in this regard. The author emphasizes that it is important to keep

Reactions between lactic acid and alcohols or carboxylic acids catalyzed by lipase from Candida antarctica were evaluated with hexane as solvent. Lactic acid was a good acyl donor and esters of both primary and secondary alcohols were effectively synthesized. No interfering dimer formation due to lactic acid acting as both nucleophile and acyl donor was observed. In agreement with this, no esterif
