Relating to harmony or harmonics; concordant and producing pleasing combinations of sounds or ideas.
From Greek harmonikos (fitting together, in harmony) + -al suffix. This Greek-derived term emphasizes both musical harmony and metaphorical concordance, with roots in ancient music theory.
Before we had 'harmonic,' musicians and scholars used 'harmonical' to describe both the math of sound waves and the philosophy of universal order—the word literally connected physics and poetry.
