Abstract/OtherAbstract:
Singing requires accurate control of the fundamental frequency (F0) of the voice. Previous work has demonstrated that F0 control involves an interplay between closed- and open-loop control. A frequency-altered auditory feedback (FAF) paradigm was used to examine the acoustic-motor representation of the mapping between F0 feedback and the vocal production system in singers and nonsingers. Participants sang a note while hearing their F0 shifted down one semitone. Both singers and nonsingers compensated for the F0 perturbations by increasing their F0. However, the magnitude of compensations was initially smaller in singers than nonsingers. Moreover, after participants heard their feedback returned to normal, the aftereffects observed for singers were larger than those observed for nonsingers. This pattern of aftereffects generalized to the production of another note different than the one participants produced while hearing FAF. Combined, these observations suggest that singers rely more on an internal model for F0 production during singing than nonsingers.
