Effects of Straw Phonation and Neutral Vowel Protocols on the Choral Sound of Two Matched Women’s Choirs

Many choral teacher-conductors and voice professionals utilize semioccluded vocal tract (SOVT) exercises (e.g., lip trills, straw phonation) in their classrooms or studios. Research with individual singers has indicated that these techniques may increase “vocal economy,” boosting acoustic output while reducing singer effort. Recently, researchers have investigated these phenomena in choral settings, finding that choirs have maintained or increased spectral energy after straw phonation. Most chorister participants have perceived improved choral sound and vocal efficiency after the protocols. These investigations, however, have used one-group pretest-posttest designs. Therefore, results could reflect a “masterclass effect.” The purpose of this study was to compare acoustic output and listener perceptions of pre- and posttest measurements of two matched women’s choirs who engaged in (a) a straw phonation protocol or (b) an identical protocol performed on a neutral, unoccluded vowel (“ah”). Results indicated that both groups sang with more spectral energy after the protocols, and a majority of expert listeners noted these increases. However, the straw group’s increase was more than 1 dB SPL greater across the entire spectrum (0–10 kHz). Choral teacher-conductors and music teacher educators may wish to use straw phonation exercises to increase choral output and reduce vocal effort.

Voice Change and Singing Experiences of Adolescent Females

The purpose of this qualitative study was to understand how undergraduate- and graduate-level choristers perceived the influence of adolescent female voice change on their singing experiences since the age of 11 years old. Data included individual and focus group interviews with 17 female collegiate choral singers enrolled in one of two women’s choirs at a large midwestern university. Three overarching themes emerged: perceptions of vocal development, teacher influence, and emotion. Findings revealed that participants’ perceptions of singing experiences since age 11 largely revolved around vocal challenges, fear, and insecurity and have remained mostly negative even after the passing of time. Experiences in choir were not necessarily positive, and participants perceived their individual vocal needs as secondary to the needs of the larger choral ensemble. Out of fear of hurting the larger choir, participants remained passive and did not self-advocate, resulting in additional challenges with self-confidence and struggles pertaining to singer identity development during adolescence and into adulthood.

A Grounded Theory of Adolescent High School Women’s Choir Singers’ Process of Social Identity Development

The purpose of this grounded theory study was to discover the process of social identity development for adolescent high school women’s choir participants. Purposive maximum variation sampling was used to identify three public high school women’s choirs where 54 interviews were conducted with 40 different public school singers. Three waves of data collection and analysis revealed a seven-step process beginning with coming in singing and ending with envisioning myself. The central phenomenon was identified as opening up my voice and me and emphasized singers’ increased self-confidence. Intervening conditions included competition, the absence of choral opportunities, and lack of understanding from those outside of the choral program. Amount of time in the choral program, number of groups, and community recognition were identified as contextual conditions. Dimensionalized properties, a temporal matrix, and propositional statements are presented.
