This article examines the mysteries and magic of the human vocal system which is small but complex. Sound is made by the vibrating vocal folds of the larynx and the resonator is the airway through which it moves. The adjustability of the vocal cords in the larynx and the stringlike ligament that is at the center of each vocal cord enables the wide ranges of octaves and sounds that humans can make.

The oscillation of the vocal cords serves to modulate the pressure and the air through the larynx, and this modulated air is the main component of the sound.
The Extra-Normal Voice: EVT in Singing.
The human voice is a remarkable instrument that encompasses enormous bio-acoustic diversity. Whether singing in folk, world, popular, classical, contemporary, experimental or improvisatory settings
Vocal Features of Song and Speech: Insights from Schoenberg's Pierrot Lunaire
By examining the relationship between the vocal features and the impression of song or speech, the results confirm the importance of pitch, but also point to the relevance of register, timbre, tension and faucal distance.
Modeling source-filter interaction in belting and high-pitched operatic male singing.
Nonlinear source-filter theory is applied to explain some acoustic differences between two contrasting male singing productions at high pitches: operatic style versus jazz belt or theater belt.
Soprano singing in gibbons.
In gibbons, dynamic control over the vocal tract configuration, rather than anatomical modifications, has been a dominant factor in determining call structure, allowing monogamous gibbons to produce pure-tonal melodious songs in the dense tropical forests with poor visibility.
The motor origins of human and avian song structure
This work hypothesizes that certain aspects of melodic shape stem from motor constraints on song production rather than being innately specified, and makes specific predictions about shared and distinct features of human and avian song structure that are confirmed by empirical analysis of diverse human andAvian song samples.
Finite-element modeling of vocal fold self-oscillations in interaction with vocal tract: Comparison of incompressible and compressible flow model
Finite-element modeling of self-sustained vocal fold oscillations during voice production has mostly considered the air as incompressible, due to numerical complexity. This study overcomes this
Study on Optimal Position and Covering Pressure of Wearable Neck Microphone for Continuous Voice Monitoring
A skin-attachable neck microphone with a lightweight and flexible form factor that provides a solution to keep the vocal cords in good health even in a noisy environment and the signal sensitivity is the highest when the covering pressure is approximately 4 mmHg.
Singing pedagogy and contemporary vocal music: A troubled relationship
In this paper, we explore the interrelationships between knowledge construction in the field of Vocal Pedagogy and compositional forms of the academic music of the 20 century. We propose that
