The antonyms for the word "in-harmonies" are "harmonies" and "agreements". When something is in-harmony, it is not in agreement, and there are conflicting aspects that create disharmony. This term is often used to describe musical compositions that lack harmony and melody, creating discordant and unappealing sounds. However, it can also refer to social or interpersonal situations that are not in accord, where there is disagreement, tension, or discord. In contrast, harmonies represent a balance and agreement between different elements, whether in music or life. Rather than discord, harmonies imply a sense of unity, collaboration and balance that creates a pleasing and satisfying effect.
