Vocal loading is the stress inflicted on the speech organs when speaking for long periods.
Overtone singing, also known as overtone chanting, harmonic singing, polyphonic overtone singing, or diphonic singing, is a set of singing techniques in which the vocalist manipulates the resonances of the vocal tract to arouse the perception of additional separate notes beyond the fundamental frequency that is being produced.
Singing is the act of creating musical sounds with the voice. A person whose profession is singing is called a singer, artist or vocalist. Singers perform music that can be sung with or without accompaniment by musical instruments. Singing is often done in an ensemble of musicians, such as a choir. Singers may perform as soloists or accompanied by anything from a single instrument up to a symphony orchestra or big band. Different singing styles include art music such as opera and Chinese opera, Indian music, Greek music, Japanese music, and religious music styles such as gospel, traditional music styles, world music, jazz, blues, ghazal, and popular music styles such as pop, rock, and electronic dance music.
Vocal cord nodules are bilaterally symmetrical benign white masses that form at the midpoint of the vocal folds. Although diagnosis involves a physical examination of the head and neck, as well as perceptual voice measures, visualization of the vocal nodules via laryngeal endoscopy remains the primary diagnostic method. Vocal fold nodules interfere with the vibratory characteristics of the vocal folds by increasing the mass of the vocal folds and changing the configuration of the vocal fold closure pattern. Due to these changes, the quality of the voice may be affected. As such, the major perceptual signs of vocal fold nodules include vocal hoarseness and breathiness. Other common symptoms include vocal fatigue, soreness or pain lateral to the larynx, and reduced frequency and intensity range. Airflow levels during speech may also be increased. Vocal fold nodules are thought to be the result of vocal fold tissue trauma caused by excessive mechanical stress, including repeated or chronic vocal overuse, abuse, or misuse. Predisposing factors include profession, gender, dehydration, respiratory infection, and other inflammatory factors.
A vocal register is a range of tones in the human voice produced by a particular vibratory pattern of the vocal folds. These registers include modal voice, vocal fry, falsetto, and the whistle register. Registers originate in laryngeal function. They occur because the vocal folds are capable of producing several different vibratory patterns. Each of these vibratory patterns appears within a particular range of pitches and produces certain characteristic sounds.
A hoarse voice, also known as dysphonia or hoarseness, is when the voice involuntarily sounds breathy, raspy, or strained, or is softer in volume or lower in pitch. A hoarse voice can be associated with a feeling of unease or scratchiness in the throat. Hoarseness is often a symptom of problems in the vocal folds of the larynx. It may be caused by laryngitis, which in turn may be caused by an upper respiratory infection, a cold, or allergies. Cheering at sporting events, speaking loudly in noisy situations, talking for too long without resting one's voice, singing loudly, or speaking with a voice that is too high or too low can also cause temporary hoarseness. A number of other causes for losing one's voice exist, and treatment is generally by resting the voice and treating the underlying cause. If the cause is misuse or overuse of the voice, drinking plenty of water may alleviate the problems.
Throat singing refers to several vocal practices found in different cultures worldwide. These vocal practices are generally associated with a certain type of guttural voice that contrasts with the most common types of voices employed in singing, which are usually represented by chest (modal) and head registers. Throat singing is often described as producing the sensation of more than one pitch at a time, meaning that the listener perceives two or more distinct musical notes while the singer is producing a single vocalization.
A vocal coach, also known as a voice coach, is a music teacher, usually a piano accompanist, who helps singers prepare for a performance, often also helping them to improve their singing technique and take care of and develop their voice, but is not the same as a singing teacher. Vocal coaches may give private music lessons or group workshops or masterclasses to singers. They may also coach singers who are rehearsing on stage, or who are singing during a recording session. Vocal coaches are used in both classical music and in popular music styles such as rock and gospel. While some vocal coaches provide a range of instruction on singing techniques, others specialize in areas such as breathing techniques or diction and pronunciation.
Vocal pedagogy is the study of the art and science of voice instruction. It is used in the teaching of singing and assists in defining what singing is, how singing works, and how proper singing technique is accomplished.
There is no authoritative system of voice classification in non-classical music as classical terms are used to describe not merely various vocal ranges, but specific vocal timbres unique to each range. These timbres are produced by classical training techniques with which most popular singers are not intimately familiar, and which even those that are do not universally employ them.
Contemporary commercial music or CCM is a term used by some vocal pedagogists in the United States to refer to non-classical music. This term encompasses jazz, pop, blues, soul, country, folk, and rock styles.
The vocal fry register is the lowest vocal register and is produced through a loose glottal closure that permits air to bubble through slowly with a popping or rattling sound of a very low frequency. During this phonation, the arytenoid cartilages in the larynx are drawn together, which causes the vocal folds to compress rather tightly and become relatively slack and compact. This process forms a large and irregularly vibrating mass within the vocal folds that produces the characteristic low popping or rattling sound when air passes through the glottal closure. The register can extend far below the modal voice register, in some cases up to 8 octaves lower, such as in the case of Tim Storms who holds the world record for lowest frequency note ever produced by a human, a G−7, which is only 0.189 Hz, inaudible to the human ear.
Professor Janice L. Chapman AUA [born January 1938 ]MOA is an Australian-born soprano, voice researcher, and vocal consultant. She is the author of Singing and Teaching Singing: A Holistic Approach to Classical Voice first published by Plural Publishing Inc. at the end of 2005, and she has contributed to papers in the Journal of Voice, The Journal of the Acoustical Society of America and Australian Voice. She is also a professor of voice at the Guildhall School of Music and Drama in London.
Estill Voice Training is a program for developing vocal skills based on analysing the process of vocal production into control of specific structures in the vocal mechanism. By acquiring the ability to consciously move each structure the potential for controlled change of voice quality is increased.
HearFones is an acoustic, non-electronic instrument that enables a person speaking or singing to hear the actual sound they are producing. The device is used by professional singers and has also been used in therapy for those with auditory issues.
In vocal music, the term voce faringea describes a historical singing practice developed and used especially by the bel canto tenors of the late eighteenth and early nineteenth century to extend the upper range of the voice by modifying the falsetto, which is typically heard as a weak or feminine sound, into a vocal quality that is more tenoral and powerful.
Muscle tension dysphonia (MTD) was originally coined in 1983 by Morrison and describes a dysphonia caused by increased muscle tension of the muscles surrounding the voice box: the laryngeal and paralaryngeal muscles. MTD is a unifying diagnosis for a previously poorly categorized disease process. It allows for the diagnosis of dysphonia caused by many different etiologies and can be confirmed by history, physical exam, laryngoscopy and videostroboscopy, a technique that allows for the direct visualization of the larynx, vocal cords, and vocal cord motion.
