Ratings of Violin and Viola Vibrato Performance in Audio-Only and Audiovisual Presentations

Abstract

In this study, the researcher compared the ratings assigned to audio and videotaped vibrato performances of inexperienced and experienced violinists and violists. Thirty-three inexperienced players and 28 experienced players were videotaped white performing vibrato. A panel of experts rated the videotaped performances and then 6 months later rated the audio-only portion of the performances on five vibrato factors: width, speed, evenness, pitch stability, and overall sound. Experienced players' vibrato was rated higher for all factors, regardless of mode of presentation. In addition, results revealed significantly higher audiovisual ratings for pitch stability, evenness, and overall sound for inexperienced players, and for pitch stability for experienced players. Results suggest that string teachers need to occasionally listen to their students' vibrato without watching them since visual cues may inadvertently influence their evaluation of student achievement.
