A musician who plays music with a rhythm that emphasizes off-beats, often found in jazz and dance music.
The syncopator added a lively beat to the jazz band, making everyone want to dance.
Syncopator → It is formed from "syn-" (meaning together) and "copa" (from Latin "cōpāre", meaning to cut or shorten). The suffix "-tor" (meaning one who) indicates a person who performs an action. Thus, a syncopator is someone who cuts or shortens music or speech together, creating a rhythmic effect.
Think of someone 'cutting' ('copa') music or speech 'together' ('syn-') — that's what a syncopator does.
