The Case for Acoustic Registers, & Mapping and Motivating the Necessary Migrations of Sound and Sensation Across Range

Registers: Laryngeal or Acoustic?
It is clear that vocal fold mass, length, and tension must vary with pitch to accomplish with functional efficiency (ratio of input to output power) the wide pitch range singers need. This voice source process is termed laryngeal registration. While much attention and debate continue in regard to the specifics of laryngeal registration, it is well-established that there are two primary laryngeal vibrational modes—one that involves short, thick folds with a loose cover and includes muscle mass vibration, and one that involves long, thin, folds, a taut cover, and is primarily ligamentous vibration. “In the wild” these two modes typically present as rather binary options. A primary goal of training for many vocal genres is to reduce or eliminate this binarity and supplant it with a smooth, dynamic laryngeal registration across range.
The historic definition of a vocal register requires relatively homogenous timbral range segments produced by specific, discrete “mechanisms.” This was based on the assumption that the timbral shifts signaling a change of register were caused by changes in the voice source, indeed, that the “mechanism” of timbral change was exclusively laryngeal. This course will explain the timbral contributions and limitations of laryngeal input and compare them to those arising from the acoustic relationships between voice source inherent harmonics and the resonances of the vocal tract. It proposes that, although bio-mechanical changes of the voice source must occur for and are vital to range access, the timbral shifts that occur across range in a well-trained, smoothed (no longer binary) voice, are primarily to exclusively due to changing acoustic relationships between the source and the filter, and therefore constitute acoustic registers, rarely clearly discrete laryngeal registers.
Mapping and Motivating the Necessary Migrations of Sound and Sensation Across Range
We will briefly review the acoustic soundscape all singers, regardless of genre, inhabit, and present studio friendly techniques for exploring how best to tune the vocal tract for functionally efficient singing. We will draw on the deep level programming of humans for activating voice and the more recently identified auditory and somatosensory targets, detailing the migrations of vowel, timbre, vibrotactile and acoustic sensation we experience across range. Knowing, anticipating, allowing, and even facilitating these migrations greatly improves smooth, dynamic laryngeal registration across range.
Use of Intention, Affect and the Chiaroscuro Whisper
Humans activate voice in response to the impulse to express feelings. When also using language, we include learned auditory targets comprised primarily of the two vowel-like timbral components featured by the first two resonances of the vocal tract. The resonance structure or sound transfer characteristics of the vocal tract can be revealed and played by introducing any broad-spectrum noise into it, such as a vocal fry. A strategy that I call the chiaroscuro whisper is especially useful for gaining aural and kinesthetic facility in this process. Unlike the typical, high-larynxed, high-pitched whisper, the chiaroscuro whisper uses a relatively neutral, settled larynx and a carefully tuned, lower-pitched noise. It is done with motivational expression, sufficient but minimal articulation that avoids over-articulating the vowel shapes or changes, and a strong, broad spread of spectral frequencies, so that both the lower pitched under-vowel noise and the higher pitched over-vowel noise are present and balanced in the composite sound output.

Money Notes for Days: Sustainable Singing for Popular Styles
Meredith Colby
In this workshop, you’ll begin to train your ears to what you’ve been missing in popular styles. We’ll identify the 'it' factor, and learn how it can be the magic to sustainable high, rock 'belt'; the sound singers of contemporary music theatre, R&B, indie, rock and jazz, and your singer-songwriters nearly all want to achieve.

Singing for Lung Health: The Basics
Dr Rachel B. Goldenberg
According to a 2016 study, nearly 1 in 5 people living in the UK have received a diagnosis of lung disease, making it highly likely that clinicians and voice teachers will encounter a singer living with a lung disease. In this presentation, we will explore the current available research and theories about why singing is beneficial to people living with impairments in the respiratory system.

SOVT Exercises: What, How, When, and Why?
John Nix
SOVTs (Semi-occluded vocal tract postures or exercises) have become widely used by singing teachers and voice therapists. Professor Nix's presentation will begin by defining and describing the various kinds of SOVTs...
