Abstract

In voice pedagogy, vocal control is a fundamental concept referring to the conscious, balanced, and functional management of the physiological, acoustic, and perceptual components involved in the voice production process. While traditionally conveyed through metaphorical approaches, this skill has acquired a measurable and systematically teachable structure with advances in contemporary voice science. In this context, the ways in which Estill Voice Training (EVT), Speech Level Singing (SLS), and Complete Vocal Technique (CVT) -widely used in contemporary literature-approach vocal control constitute an important area of inquiry. The aim of this research is to comparatively examine these three approaches within the context of vocal control. The research aims to present a holistic theoretical framework to voice educators by exploring how these approaches conceptualize vocal control, the levels of anatomical awareness they are based on, and how they structure it within pedagogical processes. Designed as a qualitative research study, document analysis was used as the primary data collection method. The data set consists of foundational methodological books, pedagogical materials, and peer-reviewed articles retrieved from international databases (Scopus, Web of Science, etc.) related to EVT, SLS, and CVT. The obtained data were analyzed using thematic content analysis combining deductive and inductive strategies. In the analysis process, data were categorized under the themes of anatomical awareness level, vocal control mechanisms, pedagogical tools, and fields of application, and evaluated through a comparative matrix. The research findings indicate that the examined approaches structure vocal control within different pedagogical priorities. Estill Voice Training demands a high level of anatomical awareness and an analytical process based on vocal control on the independent and conscious management of laryngeal structures (isolated muscle control). In contrast, Speech Level Singing centers on speech-based natural coordination and relaxation, structuring anatomical control as an indirect and perceptual process; it aims to reduce tension during register transitions. Complete Vocal Technique, on the other hand, offers a rule-based structure with high technical clarity that systematizes vocal control through four defined vocal modes (neutral, curbing, overdrive, edge) and technical parameters. The study concludes that vocal control is not a uniform skill; it is shaped by different pedagogical logics: anatomical-analytical in EVT, perceptual-coordinational in SLS, and systemic-technical in CVT. It was concluded that these approaches are not mutually exclusive, but are complementary models that meet different learning needs (anatomical precision, sustainability, or technical power). It is recommended that voice educators adopt a flexible and holistic teaching strategy that combines the strengths of these approaches according to the student’s cognitive state and musical goals, rather than adhering to a single method.

Özet

Ses eğitimi pedagojisinde vokal kontrol, ses üretim sürecine dahil olan fizyolojik, akustik ve algısal bileşenlerin bilinçli ve dengeli yönetimini ifade eden temel bir kavramdır. Geleneksel yöntemlerde daha çok metaforik yaklaşımlarla aktarılan bu beceri, günümüz ses bilimindeki gelişmelerle birlikte ölçülebilir ve sistematik olarak öğretilebilir bir yapıya kavuşmuştur. Bu bağlamda, güncel literatürde yaygın olarak kullanılan Estill Voice Training (EVT), Speech Level Singing (SLS) ve Complete Vocal Technique (CVT) yaklaşımlarının vokal kontrolü ele alış biçimleri önemli bir araştırma konusudur. Bu çalışmanın amacı, söz konusu üç yaklaşımı vokal kontrol bağlamında karşılaştırmalı olarak incelemektir. Araştırmada, bu yaklaşımların vokal kontrolü nasıl kavramsallaştırdığı, hangi anatomik farkındalık düzeyine dayandırdığı ve pedagojik süreçlerde nasıl yapılandırdığı irdelenerek, ses eğitimcilerine bütüncül bir teorik çerçeve sunulması hedeflenmektedir. Nitel araştırma deseninde tasarlanan bu çalışmada, veri toplama aracı olarak doküman incelemesi yöntemi kullanılmıştır. Araştırmanın veri setini, EVT, SLS ve CVT yaklaşımlarına ait temel metodolojik kitaplar, öğretim materyalleri ve konuyla ilgili uluslararası veri tabanlarında (Scopus, Web of Science vb.) taranan hakemli makaleler oluşturmaktadır. Elde edilen veriler, tümdengelim ve tümevarım stratejilerini birleştiren tematik içerik analizi ile incelenmiştir. Analiz sürecinde veriler; anatomik farkındalık düzeyi, vokal kontrol mekanizmaları, pedagojik araçlar ve uygulama alanları temaları altında kategorize edilerek karşılaştırmalı bir matris üzerinden değerlendirilmiştir. Araştırma bulguları, incelenen yaklaşımların vokal kontrolü farklı pedagojik öncelikler çerçevesinde yapılandırdığını göstermektedir. Estill Voice Training, vokal kontrolü laringeal yapıların bağımsız ve bilinçli yönetimi (izole kas kontrolü) üzerine kurarak yüksek düzeyde anatomik farkındalık ve analitik bir süreç talep etmektedir. Buna karşın Speech Level Singing, konuşma temelli doğal koordinasyon ve rahatlamayı merkeze alarak anatomik kontrolü dolaylı ve algısal bir süreç olarak yapılandırmakta; register geçişlerinde gerilimi azaltmayı hedeflemektedir. Complete Vocal Technique ise vokal kontrolü tanımlanmış dört vokal mod (neutral, curbing, overdrive, edge) ve teknik parametreler üzerinden sistematize eden, kural tabanlı ve teknik netliği yüksek bir yapı sunmaktadır. Çalışma sonucunda, vokal kontrolün tek tip bir beceri olmadığı; EVT’de anatomik-analitik, SLS’de algısal-koordinasyonel ve CVT’de sistemsel-teknik olmak üzere farklı pedagojik mantıklarla şekillendiği belirlenmiştir. Bu yaklaşımların birbirini dışlayan değil, farklı öğrenme ihtiyaçlarını (anatomik kesinlik, sürdürülebilirlik veya teknik güç) karşılayan tamamlayıcı modeller olduğu sonucuna varılmıştır. Ses eğitimcilerinin, tek bir yönteme bağlı kalmak yerine, öğrencinin bilişsel durumuna ve müzikal hedeflerine göre bu yaklaşımların güçlü yönlerini birleştiren esnek ve bütüncül bir öğretim stratejisi izlemeleri önerilmektedir.
