TITLE:

Tuning accuracy in singing: A study on internal models and imagery

SUMMARY:

Singing is a highly complex activity that involves several cognitive processes, among which sensorimotor integration stands out. In addition, it requires the constant updating of internal models – non-static models that represent the body's interactions with the external environment and that undergo constant recalibration during the individual's life according to experiences and learning. The Multimodal Imagery Association Model proposes that auditory imagery acts as priming for motor imagery, and vice versa, so that the ability to create mental images of the material to be sung would be essential for accuracy in vocal imitation. This study aims to verify whether auditory imagery (assessed through subjective measures of control and vividness) is related to better performance in vocal imitation tasks (assessed through accuracy in pitch in terms of fundamental frequency deviations – Fo), and whether there are associations between these measures and musicality indices. For these purposes, two experiments were carried out. In Experiment 1, conducted at the Human Cognition Laboratory of the Universidade Federal do ABC, 15 participants listened to and vocalized 20 melodies from different musical contexts (tonal and atonal) in two conditions: after a short silence time interval (4 seconds) – in which participant should mentalize the heard melody – and after a distractor task. It was observed that the accuracy in the vocal imitation task was higher after the distractor task, with smaller Fo deviations (p=0.027), and that the level of musicality is one of the factors associated with greater vividness in imagery. In Experiment 2, carried out through an online platform, participants performed a task of vocal imitation of 30 melodies (in major, minor, and atonal contexts) in two conditions: after a short silence time interval (4 seconds) to mentalize the heard melody (as in Experiment 1) and immediately after listening to the melody. 137 volunteers (non-singers, amateur singers, and professional singers) participated in this experiment. Our findings indicate that the performance in the vocal imitation task was better in the three groups, with smaller Fo deviations, in the condition without mentalization time (Z=1033.0, p<0.001). There was a significant difference between tonal and atonal contexts (Q=11.58, p=0.003) with Nemenyi's post-hoc analysis indicating significant differences between major and minor contexts (p=0.002) and between major and atonal contexts (p=0.042). There was also a moderate correlation between imagery skills and accuracy in tuning (smaller Fo deviations; ρ=-0.383). We also found significant correlations between musicality levels and imagery control (ρ=-0.592). We conclude that exposure to music and vocal experimentation, even in non-formal contexts, contributes to the updating of internal models, facilitating sensorimotor integration and the consequent ability to imitate melodies, and that the training of clear mentalization must be accompanied by good internal models to be able to be effective.
