three notes agreeing to mean something none could say alone.
means A group of notes sounded together as a single harmonic unit, or, in geometry, a straight line joining two points on a curve.
from A spelling tangle: the musical 'chord' began as 'cord,' a shortening of 'accord' (from Latin 'cor,' heart — notes that agree in feeling). The silent 'h' was added later by mistaken analogy with 'chord' in the geometric and anatomical senses, which come straight from Greek 'khordē,' meaning gut or string — the very gut once stretched across a lyre to make a tone. So the heart of harmony and the string that sings it converged on one borrowed letter.
