Meaning of CHORD in English
Grouping of three or more musical tones, especially as sounded simultaneously.
The tones C-E–G constitute a "C major chord," or "C major triad." Chords may comprise any number of separate tones, and may be highly dissonant (see consonance and dissonance ). The term harmony is often used loosely as a synonym.
