Tremolo
noun /ˈtrɛm.ə.loʊ/ — A trembling effect produced by rapid repetition of a note.
Definition
A rapid repetition of a single note or alternation between two notes, creating a trembling, shimmering effect. In film scores, it signals dread or agitation. In strings and piano, it creates sustained intensity.
Beyond the definition
Tremolo is the sound of unresolved tension — a held breath, a quivering. Horror film composers know this: tremolo strings signal that something terrible is about to happen.
Origin & history
Italian: from 'tremolare' (to tremble); from Latin 'tremulus' (trembling). Distinct from vibrato, which is a fluctuation of pitch rather than a repetition.
