We are developing a violin-playing robot which can communicate with human through playing the violin expressively. In this paper, we focus on “vibrato”, which is one of the most popular technique for playing the violin. In order to reveal the sound characteristics of vibrato, we conducted experiments with three trained violinists, in which, we asked them to play the sound of D5 with vibrato and analyzed the sound with FFT. Also, we recorded the sound of a short famous musical piece in three conditions. As a result of the sound analysis, we found that the values of the frequency fluctuation in vibrato vary from 2 Hz to 6 Hz. Then we analyzed their playing based on a questionnaire, and we found 5 patterns on musical notes to which the vibrato should be applied.
