  • 1. Lau, Hiu Yan Crystal Objective Measure of Two Musical Interpretations of an Excerpt from Berlioz's "La Mort d'Ophelie"

    Master of Science (MS), Bowling Green State University, 2020, Interdisciplinary Studies

    Objective: Art song is a unique genre in the realm of European classical music, which embraces the combined beauty of vocal melody, instrumental accompaniment, and text. In a performance context, the same composition can be performed with a variety of emotional interpretations. The purpose of this study was to determine sound production differences relative to two emotional interpretations in performing an excerpt from a classical art song. Methods/Design: The first author, a soprano with a master's degree in vocal performance, recorded an excerpt from “La Mort d'Ophelie” composed by Hector Berlioz (1803-69). The excerpt was sung in two contrasting musical interpretations: an “empathetic legato” approach, and a “sarcastic” approach with emphatic attacks. Microphone, airflow (Glottal Enterprises MSIF-2), and electroglottography (EGG; Kay Model 6103) signals were digitized. These recordings were analyzed for acoustic, airflow, and glottographic measures. The vowels in the musical excerpt were analyzed in terms of intensity, long term average spectra (LTAS), fundamental frequency vibrato rate and extent, vowel onset, intensity comparison of harmonic frequencies, and glottal measures based on electroglottograph waveforms. Results & Conclusions: Data analyses revealed that stressed vowels, when performed with the emphatic approach compared to the legato approach, had faster vowel onset, increased glottal adduction (relative to the EGGW25 measure), increased intensity of harmonics in the 1500 to 3000 Hz range, inferred increase in subglottal pressure, increased airflow for the /f/ consonant, and greater aspiration airflow for the plosives /t/ and /p/. The vibrato extent for both fo and airflow were both greater for the emphatic approach. Findings also revealed larger amplitude values of the EGG waveform, but this finding was not statistically significant. Long-term average spectrum (LTAS) analyses of the entire production displayed minor increases across all fo (open full item for complete abstract)
