Chest Voice
Chest voice is a term used within vocal music. The use of this term varies widely within vocal pedagogical circles. There is no consistent opinion among vocal music professionals regarding the term. Chest voice can be used in relation to: * A particular part of the vocal range or type of vocal register * A vocal resonance area * A specific vocal timbre History The first recorded mention of the term chest voice was around the 13th century, when it was distinguished from the throat and the head voice ( pectoris, guttoris, capitis—at this time it is likely head voice referred to the falsetto register) by the writers Johannes de Garlandia and Jerome of Moravia.''The New Grove Dictionary of Music & Musicians''. Edited by Stanley Sadie, ''Volume 6. Edmund to Fryklund''. , Copyright Macmillan 1980. The term was later redefined during the bel canto period when it was identified as the lowest of three vocal registers: the chest, passaggio and head registers. This approach is still t ...

Vocal Music
Vocal music is a type of singing performed by one or more singers, either with instrumental accompaniment, or without instrumental accompaniment (a cappella), in which singing provides the main focus of the piece. Music which employs singing but does not feature it prominently is generally considered to be instrumental music (e.g. the wordless women's choir in the final movement of Holst's symphonic work '' The Planets'') as is music without singing. Music without any non-vocal instrumental accompaniment is referred to as ''a cappella''. Vocal music typically features sung words called lyrics, although there are notable examples of vocal music that are performed using non-linguistic syllables, sounds, or noises, sometimes as musical onomatopoeia, such as jazz scat singing. A short piece of vocal music with lyrics is broadly termed a song, although in different styles of music, it may be called an aria or hymn. Vocal music often has a sequence of sustained pitches that rise an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Speech And Language Pathology
Speech is the use of the human voice as a medium for language. Spoken language combines vowel and consonant sounds to form units of meaning like words, which belong to a language's lexicon. There are many different intentional speech acts, such as informing, declaring, asking, persuading, directing; acts may vary in various aspects like enunciation, intonation, loudness, and tempo to convey meaning. Individuals may also unintentionally communicate aspects of their social position through speech, such as sex, age, place of origin, physiological and mental condition, education, and experiences. While normally used to facilitate communication with others, people may also use speech without the intent to communicate. Speech may nevertheless express emotions or desires; people talk to themselves sometimes in acts that are a development of what some psychologists (e.g., Lev Vygotsky) have maintained is the use of silent speech in an interior monologue to vivify and organize cog ...

Vocal Register
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 (or normal voice), vocal fry, falsetto, and the whistle register. Registers originate in larynx, 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 Pitch (music), pitches and produces certain characteristic sounds. In speech pathology, the vocal register has three components: a certain vibratory pattern of the vocal folds, a certain series of pitches, and a certain type of sound. Although this view is also adopted by many vocal pedagogy, vocal pedagogists, others define vocal registration more loosely than in the sciences, using the term to denote various theories of how the human voice changes, both subjectively and objectively, as it moves through its pitch range. There are many divergent theo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tessitura
In music, tessitura ( , , ; ; ) is the most acceptable and comfortable vocal range for a given singer (or, less frequently, musical instrument). It is the range in which a given type of voice presents its best-sounding (or characteristic) timbre. This broad definition is often interpreted to refer specifically to the pitch range that most frequently occurs within a given part of a musical piece. Hence, in musical notation, ''tessitura'' is the ambitus, or a narrower part of it, in which that particular vocal (or less often instrumental) part lies—whether high or low, etc. However, the tessitura of a part or voice is not decided by the extremes of its range, but rather by the share of this total range which is most used. Hence, it is referred to as the "heart" of a range. For example, throughout the entirety of Wagner's '' Ring'', the music written for the tenor role of Siegfried ranges from C to C, but the tessitura is described as high because the phrases are most oft ...

Thorax
The thorax (: thoraces or thoraxes) or chest is a part of the anatomy of mammals and other tetrapod animals located between the neck and the abdomen. In insects, crustaceans, and the extinct trilobites, the thorax is one of the three main divisions of the body, each in turn composed of multiple segments. The human thorax includes the thoracic cavity and the thoracic wall. It contains organs including the heart, lungs, and thymus gland, as well as muscles and various other internal structures. The chest may be affected by many diseases, of which the most common symptom is chest pain. Etymology The word thorax comes from the Greek θώραξ ''thṓrax'' " breastplate, cuirass, corslet" via . Humans Structure In humans and other hominids, the thorax is the chest region of the body between the neck and the abdomen, along with its internal organs and other contents. It is mostly protected and supported by the rib cage, spine, and shoulder girdle. Contents The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vocal Folds
In humans, the vocal cords, also known as vocal folds, are folds of throat tissues that are key in creating sounds through Speech, vocalization. The length of the vocal cords affects the pitch of voice, similar to a violin string. Open when breathing and vibrating for speech or singing, the folds are controlled via the recurrent laryngeal nerve, recurrent laryngeal branch of the vagus nerve. They are composed of twin infoldings of mucous membrane stretched horizontally, from back to front, across the larynx. They vibration, vibrate, modulating the flow of air being expelled from the lungs during phonation. The 'true vocal cords' are distinguished from the 'false vocal folds', known as vestibular folds or ''ventricular folds'', which sit slightly superior to the more delicate true folds. These have a minimal role in normal phonation, but can produce deep sonorous tones, screams and growls. The length of the vocal fold at birth is approximately six to eight millimeters and grows t ...

Electroglottograph
The electroglottograph, or EGG, (also referred to as a laryngograph) is a device used for the noninvasive measurement of the degree of contact between the vibrating vocal folds during voice production. Though it is difficult to verify the assumption precisely, the aspect of contact being measured by a typical EGG unit is considered to be the vocal fold contact area (VFCA). To measure VFCA, electrodes are applied on the surface of the neck so that the EGG records variations in the transverse electrical impedance of the larynx and nearby tissues by means of a small A/C electric current (in megaHertz). This electrical impedance will vary slightly with the area of contact between the moist vocal folds during the segment of the glottal vibratory cycle in which the folds are in contact. However, because the percentage variation in the neck impedance caused by vocal fold contact can be extremely small and varies considerably between subjects, no absolute measure of contact area is obtai ...

Cricothyroid Muscle
The cricothyroid muscle is the only tensor muscle of the larynx aiding with phonation. It is innervated by the superior laryngeal nerve. Its action tilts the thyroid forward to help tense the vocal cords, thus increasing the pitch of the voice. Structure The cricothyroid muscle is a fan-shaped muscle situated at the outer surface of the larynx. Origin The cricothyroid muscle originates from the anterolateral aspect of the cricoid cartilage. Insertion The cricothyroid muscle splits into two groups or parts. The oblique part travels posterolaterally and inserts onto the inferior cornu of the thyroid cartilage. The straight part travels posterosuperiorly and inserts onto the inferior margin of the lamina of the thyroid cartilage. Innervation The cricothyroid muscle is innervated by the external branch of the superior laryngeal nerve (a branch of the vagus nerve). It is the only muscle innervated by this nerve. Function The cricothyroid muscle produces tension and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thyroarytenoid Muscle
The thyroarytenoid muscle is a broad, thin muscle that forms the body of the vocal fold and that supports the wall of the ventricle and its appendix. It functions to shorten the vocal folds. Structure It arises in front from the lower half of the angle of the thyroid cartilage, and from the middle cricothyroid ligament. Its fibers pass backward and laterally, to be inserted into the base and anterior surface of the arytenoid cartilage. Parts The lower and deeper fibers of the muscle can be differentiated as a triangular band which is inserted into the vocal process of the arytenoid cartilage, and into the adjacent portion of its anterior surface; it is termed the ''Vocalis'', and lies parallel with the vocal ligament, to which it is adherent.Frank H. Netter, MD "Atlas of Human anatomy", 7th Edition, 2019, Plate 91, superior view The vocal muscle is the upper portion of the thyroarytenoid muscle which is primarily involved in producing speech. A considerable number of the fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phonation
The term phonation has slightly different meanings depending on the subfield of phonetics. Among some phoneticians, ''phonation'' is the process by which the vocal folds produce certain sounds through quasi-periodic vibration. This is the definition used among those who study laryngeal anatomy and physiology and speech production in general. Phoneticians in other subfields, such as linguistic phonetics, call this process '' voicing'', and use the term ''phonation'' to refer to any oscillatory state of any part of the larynx that modifies the airstream, of which voicing is just one example. Voiceless and supra-glottal phonations are included under this definition. Voicing The phonatory process, or voicing, occurs when air is expelled from the lungs through the glottis, creating a pressure drop across the larynx. When this drop becomes sufficiently large, the vocal folds start to oscillate. The minimum pressure drop required to achieve phonation is called the phonation thres ...

Electroglottographic Wavegram
An electroglottographic wavegram (short: EGG wavegram) is a tool for analyzing the voice source in speech and singing, based on electroglottographic (EGG) signals (and their first derivative, DEGG). Assessing the singing and speaking voice The wavegram, invented by Christian T. Herbst, provides an intuitive means for quickly assessing vocal fold contact phenomena and their variation over time. Vocal fold closings and openings appear here as a sequence of events rather than single incidents, taking place over a certain period of time, and changing with pitch, loudness and register. Wavegrams document systematic phenomena, indicating subtle changes of the vocal fold oscillatory regime. Electroglottographic wavegrams are created in 5 steps (see illustration): # extraction of consecutive glottal cycles from the EGG signal; # locally normalized data values are converted into monochrome color information, and are plotted as a strip representing one glottal cycle each; # strips are r ...
