Investigating the Physiological and Acoustic Contrasts Between Choral and Operatic Singing

In this study, the difference in glottal vibration and timbre of singing voice in choral and operatic singing was investigated. Eight professional singers with active careers in operatic and choral performances participated in the experiment and sang excerpts from three operatic songs and two choral songs. Audio and electroglottograph signals were simultaneously recorded. The open quotient (Oq) and singing power ratio (SPR) of the voices were analyzed, and it was found that the Oq of choral singing tends to be higher and the SPR of choral singing tends to be lower than those of operatic singing. This suggests that choral singing is conducted with laxer vocal fold coordination, and it has less ringing timbre than operatic singing. However, the Oq and SPR were not directly correlated: the degree of adjustment of SPR differed across singers, suggesting that the strategy to achieve a desired voice quality is individualistic in nature.
