Práticas de vibrato do século XX: Jascha Heifetz, David Oistrakh e Fritz Kreisler

Abstract

This study examines the vibrato practices of violinists Jascha Heifetz, David Oistrakh, and Fritz Kreisler, employing spectrogram analysis to explore the technical aspects of their performances. Through the analysis of spectrograms, significant variations in the rate and depth of vibrato among these artists were identified. The research revealed that while Heifetz utilized a rapid and intense vibrato, Oistrakh was characterized by a broader, more expressive vibrato, and Kreisler by a more subdued and controlled vibrato. These findings underscore the significance of vibrato in interpretive individuality and violin technique.
