An Analysis of Double Bass Vibrato

Abstract

The purpose of this study was to investigate the rates, widths, and pitches of university double bass players’ vibrato in relation to pitch height, fingers used, and tempo. Forty ( N = 40) undergraduate and graduate double bass players performed excerpts in first, fourth, and thumb positions. The overall mean vibrato rate and width was 5.17 Hz and 19 cents. Analyses indicated that university double bassists employed faster vibrato rates and increased width as they performed in progressively higher registers. The third and fourth fingers vibrated the fastest, but the second finger produced the largest width. Musical examples played with a fast tempo were both faster and wider (5.35 Hz, 20 cents) than musical examples played with a slow tempo (4.94 Hz, 19 cents). Participants vibrated almost equally above and below the in-tune pitch—overall mean pitches of vibrated and non-vibrated tones varied by 1 cent. Music educators may use these results to create more consistent descriptions of double bass vibrato and, potentially, more efficient methods for teaching vibrato.
