Kumi wudui vocal culture

 

Ryūkyūan kumi wudui (組踊, Japanese kumi odori) uses a variety of codified vocal techniques to identify the gender and social class of each character. Degrees of musicality, variation in timbre, and pitch inflection are all understood as emblematic of particular character types.

These vocal techniques are constructed within Ryūkyūan society with reference to the Ryūkyūan language, class system, and gender relationships. Many parallels can be drawn between the ways vocal identities are constructed in kumi wudui vocal culture and in other world theater traditions.

This according to “Listening to the voice in kumiudui: Representations of social class and gender through speech, song, and prosody” by Matt Gillan (Asian music XLIX/1 [winter–spring 2018] pp. 4–33).

Below, some examples of kumi wudui vocal types.

Journal of interdisciplinary voice studies

JIVS

Launched by Intellect in 2015, Journal of interdisciplinary voice studies provides a platform for academics and practitioners involved in voice studies.

Voice is understood here as a phenomenon of different disciplines such as communication and performance, but also as a methodological tool and analytical mechanism. This journal aims to represent the wide variety of voice scholars and hopes to reflect the multifaceted nature of this subject.

Below, a project by the interactive theater collective non zero one, the subject of one of the articles in the inaugural issue.

The vocal tract organ

vocal tract organ

 

The vocal tract organ is a new musical instrument that consists of three-dimensional (3D)-printed vocal tracts (throat and mouth) for individual vowels sitting on loudspeakers to enable static vowel sounds to be produced.

The acoustic excitation from the loudspeakers is a synthesized version of the typical waveform produced by the vibrating human vocal folds during pitched sounds, which enables the instrument to be played from a keyboard.

The vocal tract organ will become an instrument in its own right, and it could be used as a direct replacement for the vox humana organ stop, given that its acoustic output is a much closer representation of the human vocal output than that from a vox humana organ pipe. The 3D-printed tracts may also be used  in vocal and choral workshops as well as degree-level music technology education.

This according to “The vocal tract organ and the vox humana organ stop” by David M. Howard (Journal of music, technology & education VII/3 [2014] pp. 265–277).

Pachyderm proclamations

Elephants can communicate using sounds below the range of human hearing (infrasounds below 20 hertz). These vocalizations have been presumed to be produced in the larynx, either by neurally controlled muscle twitching (as in cat purring) or by flow-induced self-sustained vibrations of the vocal folds (as in human speech and song).

In an experiment, direct high-speed video observations of an elephant larynx demonstrated flow-induced self-sustained vocal fold vibration in the absence of any neural signals, thus excluding the need for any purring mechanism. The observed physical principles of voice production apply to a wide variety of mammals, extending across a remarkably large range of fundamental frequencies and body sizes, spanning more than five orders of magnitude.

This according to “How low can you go? Physical production mechanism of elephant infrasonic vocalizations” by Christian T. Herbst, et al. (Science CCCXXXVII/6094 [3 August 2012] pp. 595–599). Below, a podcast interview with Dr. Herbst provides examples and further details (including the fact that the elephant had died of natural causes).
