1861年(副詞),1870年(名詞),“音樂中顫動的效果”,源自意大利語的 vibrato,從拉丁語的 vibratus 派生而來,是 vibrare “振動”的過去分詞(源自於 PIE 詞根 *weip-,表示“旋轉、擺動、狂喜地顫抖”)。
Strictly, the vibrato is distinct from the tremolo, in that the latter involves a perceptible variation in pitch; but in common usage the terms are made synonymous. [Century Dictionary]
