* Expert Performer Radar: Implications for ensemble instruction

Previous research on musical communication in orchestral performance identified the concept of performer ‘radar,’ which professional ensemble performers described as “encompassing listening to, communicating with, and adapting to other members of the ensemble at all times during rehearsal and performance” (Dobson & Gaunt, p. 30). This same research, however, did not clarify the kinds of mental or musical processes involved in ensemble radar, the kinds of errors committed by performers who lack sufficient musical radar, the processes through which ensemble radar develops, and factors that might mediate the development of ensemble radar. The purpose of this study is to clarify these issues.In this study, expert performers who regularly perform in various professional instrumental ensembles were interviewed. Interview questions were designed to clarify the performers’ focus of attention during rehearsals and performances.Preliminary results indicate that 1) focus of attention on the role in the ensemble and repertoire, 2) the performers’ primary goal was to support other performers—to make others sound better, and 3) these expert ensembles abilities were developed independently rather than as the result of explicit large ensemble instruction. Implications for cognitive apprenticeship within ensembles is discussed.
