Processing pitch and duration in music reading: a RT-ERP study

Abstract

The originality of this study is to examine the processing of pitch and duration in music reading, using both electrophysiological and behavioral methods. Specifically, it was of interest to determine whether pitch and duration in music reading are processed independently or jointly. A probe, comprising a key and time signature was presented, and participants were required to compute the tonic and/or the best fitting duration. A target note followed the probe and participants made a match/mismatch judgment on the dimension they were required to analyze (i.e. pitch or duration). We hypothesized that, if pitch and duration are processed independently results should show no interference of the irrelevant dimension on the relevant. Results showed that early differences emerged in the ERPs as a function of the task to be performed on the target in block 1. Moreover, RTs were shorter in the pitch than in the duration task and for congruous than incongruous targets. In the ERPs, this congruity effect was reflected by a negative component, to incongruous targets. Most importantly, the congruency of the target note on the irrelevant dimension did not have any effect on the ERPs, suggesting that pitch and duration are processed independently.
