Eurythmics is a proper noun referring to the British music duo known for synth-pop and new wave in the 1980s. The term itself also evokes the related modern-phonetic prefix eury- meaning broad or good, plus -thmics, and is pronounced as a two-syllable, distinct proper noun with stress on the first syllable. It’s typically used as a title or brand name rather than in ordinary speech.
