Arytenoid Cartilage – a paired, pyramid‑shaped cartilage that sits atop t… #
Related terms: Vocal folds, glottis, laryngeal muscles. The arytenoids rotate to abduct (open) or adduct (close) the vocal folds, controlling phonation onset and pitch modulation. Example: During a gentle “ah” sigh, the arytenoids slowly adduct, allowing a smooth glottal closure. Practical application in therapeutic singing: Guiding clients to feel the subtle “click” of arytenoid movement helps develop efficient breath‑to‑voice coordination. Common challenge: Excessive tension in the surrounding musculature can restrict arytenoid rotation, leading to strained phonation.
Acoustic Impedance – the resistance a medium offers to sound wave transmi… #
Related terms: Resonance, formants, vocal tract. In singing, the vocal tract’s shape alters impedance, shaping the spectral content of the voice. Example: Narrowing the pharynx raises acoustic impedance, emphasizing higher formants for bright timbre. Therapists use impedance concepts to teach clients how mouth shaping influences vocal quality. Challenge: Novice singers often over‑compress the vocal tract, creating excessive impedance and resulting in a “tight” sound.
Belting – a vocal style that employs a high, speech‑like chest resonance… #
Related terms: Chest voice, mixed voice, subglottic pressure. Practitioners describe belting as “singing with the voice of speech but at a higher pitch.” In therapeutic contexts, belting can be used to explore dynamic range and emotional expression. Example: A client may belt a sustained “ah” in the upper middle register to release tension. Challenge: Improper subglottic support can cause vocal fatigue or dysphonia; gradual buildup of stamina is essential.
Breath Support – the coordinated engagement of the diaphragm, intercostal… #
Related terms: Diaphragmatic breathing, subglottic pressure, inhalation. Effective support provides a steady airstream, enabling smooth phonation and dynamic control. Example: A therapist instructs a client to inhale to a count of four, expand the lower ribs, then exhale while sustaining a vowel, feeling the “push” from the abdomen. Practical application: Breath support exercises improve endurance for long therapeutic singing sessions. Challenge: Habitual shallow chest breathing limits airflow, requiring re‑training of diaphragmatic patterns.
Cricothyroid Muscle – the primary pitch‑raising muscle that tilts the thy… #
Related terms: Pitch regulation, laryngeal tilt, vocal folds. Activation of the cricothyroid stretches the folds, increasing tension and raising frequency. Example: When a singer ascends a scale, the cricothyroid contracts to achieve higher notes. In therapeutic singing, gentle cricothyroid activation helps clients explore higher registers without excessive strain. Challenge: Over‑activation can lead to a “tight” high register; balanced coordination with the thyroarytenoid is crucial.
Diaphragm – the dome‑shaped muscle separating thoracic and abdominal cavi… #
Related terms: Breath support, intra‑abdominal pressure, rib cage. During inhalation, the diaphragm contracts and flattens, increasing thoracic volume and drawing air into the lungs. Example: A therapist uses tactile cues on the lower ribs to help a client feel diaphragmatic descent. Practical application: Diaphragmatic breathing enhances vocal stamina and reduces laryngeal tension. Challenge: Many singers default to clavicular breathing, limiting control over subglottic pressure.
Epiglottis – a leaf‑shaped cartilage that protects the airway during swal… #
Related terms: Laryngeal inlet, vocal tract, resonance. While the epiglottis does not directly vibrate, its position affects the size of the supraglottic space. Example: A relaxed epiglottis creates a slightly open throat, facilitating a resonant “yawn” quality. In therapeutic singing, encouraging an “open throat” feeling often involves visualizing a lowered epiglottis. Challenge: Tension in the suprahyoid muscles can cause the epiglottis to elevate, narrowing the airway and producing a constricted sound.
Formant – a resonance frequency band amplified by the shape of the vocal… #
Related terms: Vowel acoustics, resonance, vocal tract length. The first two formants (F1, F2) are crucial for vowel identity; higher formants affect timbre. Example: Shaping the mouth for an “oo” vowel lowers F2, producing a darker tone. Therapists use formant awareness to help clients achieve targeted tonal colors. Challenge: Inconsistent mouth shaping leads to unstable formant patterns, affecting vowel clarity.
Glottis – the opening between the vocal folds; the site of airflow regula… #
Related terms: Vocal folds, subglottic pressure, phonation. The glottal aperture determines the amount of air that passes through, influencing both intensity and timbre. Example: A narrow glottal slit creates a breathy sound, while full closure yields a strong, clear tone. Practical application: Teaching clients to modulate glottal width aids in expressive dynamics. Challenge: Chronic incomplete closure can cause “air leakage” and vocal fatigue.
Head Voice – a resonant, higher‑register mode characterized by predominan… #
Related terms: Mixed voice, falsetto, vocal fold elongation. In head voice, the vocal folds thin and stretch, while the vocal tract expands, creating a bright, ringing quality. Example: A client sings a high “ee” vowel with a lifted, forward placement, feeling resonance in the mask. Therapeutic use: Head voice exercises develop flexibility and reduce reliance on chest register. Challenge: Students may confuse head voice with falsetto, lacking proper support and resulting in a thin sound.

Challenge: Over‑reliance on visual cues may hinder proprioceptive development; balance with internal sensations is needed.
Kinetic Chain of Voice Production – the integrated sequence of muscular a… #
Related terms: Breath support, articulation, resonance. Each segment (diaphragm, rib cage, larynx, vocal tract) influences the next, creating efficient phonation. Example: A client learns to coordinate diaphragmatic drive, laryngeal relaxation, and mouth shaping for a seamless phrase. Therapeutic application: Addressing breakdowns in the chain (e.G., Rib tension) restores vocal efficiency. Challenge: Isolating specific links without disrupting the whole system requires careful, progressive training.
Laryngeal Tilt – the forward rotation of the thyroid cartilage, decreasin… #
Related terms: Pitch control, cricothyroid muscle, vocal fold tension. Tilting the larynx lowers pitch and adds a darker timbre; excessive tilt can cause a “pharyngeal” constriction. Example: Singers may employ slight laryngeal tilt to achieve a relaxed low register. In therapeutic singing, gentle tilt exercises help clients explore lower ranges safely. Challenge: Habitual extreme tilt may lead to reduced vocal fold vibration and a muffled sound.
Mask Resonance – the acoustic phenomenon where sound energy concentrates… #
Related terms: Front resonance, vocal tract shaping, nasality. Achieving mask resonance involves an open throat, lifted soft palate, and forward tongue placement. Example: A therapist guides a client to “feel the vibration on the cheekbones” while singing an “ah” vowel. Practical use: Mask resonance enhances projection without increasing subglottic pressure, beneficial for therapeutic group singing. Challenge: Confusion with excessive nasality; proper balance is essential.
Nasality – the degree to which sound resonates in the nasal cavity; can b… #
Related terms: Velopharyngeal closure, mask resonance, oral cavity. Controlled nasality adds brightness, while hypernasality may indicate inadequate velopharyngeal closure. Example: A client singing a “ng” consonant experiences natural nasality, which can be extended to vowel singing for brightness. Therapeutic focus: Training soft palate elevation to manage nasality levels. Challenge: Clients with chronic hypernasality may develop compensatory mouth opening, affecting articulation.
Oblique Pharyngeal Wall – the lateral muscular wall of the pharynx that c… #
Related terms: Pharyngeal constriction, resonance tuning, swallowing. Adjusting the oblique wall changes the cross‑sectional area, affecting formant frequencies. Example: Narrowing the lateral walls slightly raises the first formant, sharpening vowel clarity. In therapeutic singing, gentle awareness of pharyngeal wall tension helps clients achieve balanced resonance. Challenge: Excessive constriction can cause a “squeezed” tone and limit airflow.
Phonation – the process of producing sound via vocal fold vibration drive… #
Related terms: Glottis, subglottic pressure, vocal fold vibration. Phonation requires coordinated breath support, appropriate glottal closure, and resonant shaping. Example: A sustained “oo” vowel demonstrates steady phonation when breath pressure matches vocal fold resistance. Practical application: Phonation exercises improve voice stability and are core to therapeutic singing protocols. Challenge: Irregular glottal closure leads to breathy or strained phonation; corrective feedback is often needed.
Quadrant of Vowel Space – a visual representation of vowel articulation b… #
F2). Related terms: Vowel acoustics, formants, mouth shaping. The space is divided into four quadrants (high‑front, high‑back, low‑front, low‑back), guiding singers in vowel placement. Example: Moving from “ah” (low‑back) to “ee” (high‑front) shifts the vowel point across the diagram, affecting timbre. Therapeutic use: Vowel‑space drills develop flexibility and improve intelligibility. Challenge: Clients with limited mouth opening may collapse the vowel space, reducing tonal variety.
Resonance – the amplification of sound waves as they travel through the v… #
Related terms: Formants, mask resonance, acoustic impedance. Resonance determines the voice’s richness and projection. Example: An “open throat” feeling enhances resonance, yielding a fuller sound. In therapeutic singing, resonance training helps clients achieve expressive depth without excessive force. Challenge: Over‑compression of the vocal tract lowers resonance, yielding a thin, weak tone.
Subglottic Pressure – the air pressure below the vocal folds that drives… #
Related terms: Breath support, phonation, glottal resistance. Adequate pressure ensures consistent vocal fold oscillation; insufficient pressure leads to breathy tone, while excess pressure may cause strain. Example: A therapist asks a client to sustain a note while feeling a gentle “push” from the abdomen, indicating proper subglottic pressure. Practical application: Pressure control is essential for dynamic contrast in therapeutic singing. Challenge: Clients with anxiety may over‑inflate, creating tension; gradual pressure awareness exercises are required.
Thyroarytenoid Muscle – the primary vocal fold muscle responsible for sho… #
Related terms: Vocal fold tension, chest voice, laryngeal balance. Activation of the thyroarytenoid creates a richer, darker tone by reducing vocal fold length. Example: During a chest‑voice belt, the muscle contracts to add mass to the folds. Therapeutic relevance: Balanced thyroarytenoid engagement prevents over‑reliance on cricothyroid tension. Challenge: Hyper‑activation can lead to a “pressed” sound and reduced flexibility.
Upper Vocal Tract – the portion of the vocal system extending from the gl… #
Related terms: Resonance, formants, articulation. Manipulating the shape of the upper vocal tract modifies acoustic output. Example: Expanding the oral cavity while singing “ah” produces a brighter timbre. In therapeutic singing, exercises that explore different tract configurations enhance expressive range.
