The literacy of the problem of high notes singing in Thai female singers in Thailand

Abstract

This study investigates the vocal challenges faced by Thai female singers, particularly in achieving high notes, and explores the effectiveness of Thai phonetic word sets as a pedagogical tool for developing healthy vocal techniques. Drawing on both quantitative and qualitative methods, the research includes experimental data from university-aged female students (18–25 years) and interviews with 23 experienced vocal teachers. The findings reveal sixteen common vocal problems—such as voice cracking, breathiness, and vocal fatigue—often linked to improper technique, poor vocal health awareness, and psychological factors like lack of confidence and anxiety. Singing high notes in Thai presents unique difficulties due to the tonal and monosyllabic nature of the language. Through phonetic analysis and expert consultation, the study developed a set of vocal exercises using specific Thai consonant and vowel combinations to support resonance and ease of articulation. Results from the implementation of these exercises demonstrated improved vocal control, tone production, and student confidence in navigating the upper register. The research highlights the importance of vocal health, articulation techniques, and the integration of Thai linguistic characteristics into vocal pedagogy. Additionally, the study advocates for a hybrid learning model—combining discovery-based, classroom, and private instruction—to enhance long-term vocal development. These findings contribute to the development of sustainable, culturally responsive vocal training methods suitable for Thai female singers aspiring to sing in high registers.
