The impact of vibrato usage on the perception of pitch in early music compared to grand opera
Résumé
Previous studies on the pitch of long-duration vibrato tones have typically used synthesised frequency modulated tones to assess the perceived pitch in relation to its mean fundamental frequency. In this study a listening test was conducted with expert listener subjects matching recorded vibrato tones sung by professional singers using a method of adjustment within a free response paradigm as employed by van Besouw et al. 2009. Tones from recordings by 16 singers were used in the test, 8 of whom were employed at the Royal Opera House, Covent Garden, and the remaining singers specialised in Early Music Performance. A previous study in the vibrato usage by these singers shows a noticeable difference in the use of vibrato between these performance groups, particularly in extent, throughout long tones (Daffern, 2008). The impact of these differences in vibrato will be assessed in terms of the perception of pitch in long tones as performed by the two groups of singers, and the effectiveness of using real recordings to assess listener perception of vibrato tones will be discussed.
