Estill Voice Model Pdf

Estill Voice Model (EVM) is a scientific approach to vocal training that replaces mystery with physical mechanics. Developed by

, a singer and researcher, it breaks down the complex act of vocalising into 13 isolatable "Figures for Voice". Core Concepts of the Estill Model

The model is structured around two levels: identifying individual structures and then combining them into "recipes" for specific sounds. The 13 Figures for Voice:

These are specific exercises to control different parts of the vocal tract, such as the soft palate (velum) larynx height tongue position The Power-Source-Filter Model: The system views the voice as an instrument where the provide power, the vocal folds (larynx) act as the source, and the vocal tract serves as the filter that shapes the tone. Three Disciplines of Voice:

Gaining predictable, physical control over the vocal structures. Using that craft creatively to serve music or performance. Performance Magic:

Reaching a state of flow where the performer and audience are fully connected. The Six Voice Qualities ("Recipes")

Once you master individual figures, the EVM teaches you how to combine them into six primary voice qualities used across all genres:

The Estill Voice Training (EVT) model, developed by Jo Estill, is a scientific approach to voice production that treats the voice as an instrument with independent moving parts. It shifts the focus from "how to sing" to "how the anatomy works," allowing for total control over vocal qualities without aesthetic bias. Key Concepts of the Estill Model

The model is structured around three main levels of mastery:

Compulsory Figures for Voice Control: These are exercises designed to isolate and control 13 specific anatomical structures (called "Figures"). Examples include controlling the True Vocal Folds (for onset/offset), Larynx (for pitch/resonance), and Velum (for nasality). estill voice model pdf

Six Basic Voice Qualities: By combining these figures in specific "recipes," singers and speakers can produce six distinct archetypal sounds: Speech: Neutral, everyday speaking voice.

Falsetto: Breathier, light sound with minimal vocal fold contact.

Sob: A darkened, thin-fold quality associated with a lowered larynx.

Twang: A bright, piercing quality achieved by narrowing the epiglottic funnel.

Opera: A powerful, resonant quality combining a low larynx and twang.

Belting: High-intensity, chest-dominant singing used in musical theater and pop.

The Power-Source-Filter Theory: The model adheres to the scientific principle that voice is produced by Power (breath/lungs), Source (vocal fold vibration), and Filter (vocal tract resonance). Notable Research & Papers

While "The Estill Voice Model" is often taught through official workbooks and certifications, several peer-reviewed papers discuss its efficacy and physiological basis:

"The Estill Voice Model: Its Evolution and Usage": Often cited in vocal pedagogy, this type of paper explores how Jo Estill's early research with spectrograms and EMG led to the formalization of the figures. Estill Voice Model (EVM) is a scientific approach

Physiological Studies: Research has validated Estill's "Twang" figure, showing that narrowing the aryepiglottic fold creates a "singer's formant" without increasing subglottal pressure.

Clinical Applications: Studies published in the Journal of Voice often examine how Estill Figures are used in Voice Therapy to help patients with vocal fold nodules or muscle tension dysphonia. Accessing PDFs

Official manuals are typically restricted to students enrolled in Estill Voice Training courses. However, you can find detailed academic overviews and thesis papers through:

Estill Voice International: The official site for research summaries and course materials.

Google Scholar: Search for "Jo Estill" or "Anatomical Figures for Voice" to find specific biomechanical studies.

Step 2: Isolate the Figures (No Singing!)

The Estill method starts with non-speech sounds. Use your PDF's checklist to practice:

  • Twang: The "cat scream" or "witch's cackle."
  • Sob: The inhale of a sudden cry.
  • Falsetto: The breathy sigh on a high pitch. Do not add pitch or melody until the PDF's "competency criteria" are met.

For Singing Teachers

  • Instead of saying "add more support," say "increase true fold medial compression."
  • Instead of "open your throat," say "retract false folds and lift velum."
  • Use minimal pairs (e.g., Sob vs. Cry on same pitch) to teach contrast.

1. Executive Summary

The Estill Voice Model (EVM) is a systematic, evidence-based approach to voice training developed by American singer and voice scientist Jo Estill. Unlike traditional pedagogies that rely on metaphorical imagery (e.g., "sing into the mask"), EVM focuses on voluntary control over specific physiological structures. The model deconstructs the voice into discrete, controllable parts, allowing vocalists to achieve versatility across various musical genres and speaking contexts. PDF resources regarding this model typically serve as technical manuals, research compendiums, or study guides for certification.

4. Figures for Voice

The "Figures for Voice" are specific drills designed to isolate individual muscle groups. A standard Estill PDF manual will detail the execution and anatomy of these figures. Common examples include:

  • False Vocal Folds (FVF): Learning to retract (pull back) the false vocal folds to create an open throat and prevent constriction during high-effort singing.
  • Thyroarytenoid/ Cricoarytenoid Control: Exercises to switch smoothly between TA-dominant and CT-dominant production or blend them.
  • Larynx Control: Exercises to keep the larynx at a neutral resting position, preventing the "high larynx" squeeze often associated with untrained high notes.
  • Twang: A specific configuration of the aryepiglottic sphincter that increases brightness and volume without strain. This is crucial for belting and commercial music styles.
