Musicians' and Nonmusicians' Assessment of Perceived Rubato in Musical Performance

Abstract

The purpose of this study was to investigate musicians' and nonmusicians' assessment of perceived rubato in musical performance. Music majors ( n = 48) and nonmusic majors ( n = 48) listened to four different soloists' performances of the development section of Mozart's Concerto for Horn and Orchestra No. 2, movement 1. Subjects evaluated the degree of appropriateness/inappropriateness of each soloist's use of rubato using the Continuous Response Digital Interface (CRDI), an instrument that allows ongoing evaluation of specified performance variables. Using a Likert-type scale, subjects also assessed soloists with regard to musicianship, expression, tone quality, and tempo. Results indicated significant differences for musicians compared to nonmusicians regarding rubato assessments. Musicians agreed with expert assessments, whereas non-musicians' scores seemed haphazard. When musicians were separated into two groups based on musical skill level, results from the “more proficient” musicians were in direct agreement with the panel of experts' evaluations. The “less proficient” musicians were much less discriminating across all dependent measures; rubato assessments disagreed substantially with those of experts. This study suggests that rubato is an extremely subtle musical nuance. Though nonmusicians and less proficient musicians seem to be able to assess performances on somewhat more obvious variables, it seems that only the most proficient musicians can evaluate the usage of rubato in performance. Based on the data from this study, it appears that a relationship exists between musicianship and the use of rubato and that use of rubato might well be one element that separates the very finest performance from the simply ordinary.
