Etymology

Origin of harmonize

First recorded in 1475–85; late Middle English, also armonise, from Middle French harmoniser, equivalent to harmonie + -iser, verb suffix; see harmony, -ize

Explanation

When you harmonize different opinions or ideas, you bring them to some kind of agreement.

When senators from different parties work together on a bill, they need to harmonize their different expectations and and priorities before they can come up with a good compromise. Another way to harmonize is to blend two singing voices or two instruments in a way that sounds pleasing. This is the oldest meaning of the word, which ultimately comes from the Greek harmonia, "concord of sounds" or "agreement."
