Abstract
The purpose of this study is to understand patterns by observing the acoustic characteristics of naturally produced violin vibrato through direct measurement, comparative analysis with sustained tones, and theoretical modeling. Unlike sustained tones, vibrato introduces periodic oscillations in pitch, amplitude, and harmonic content and combines them to create the timbre of the violin. A detailed analysis of bowed vibrato is conducted to explore potential relationships between vibrato and modulation of pitch, amplitude variation, and timbre shifts. Mathematical models are also used to capture these vibrato effects in the form of equations. In essence, the findings confirm the indispensable role of vibrato in forming the tonal complexity of violin sound, with info useful for improved vibrato synthesis, room acoustic optimization, and violin music education.
