Harmoni is a modern spelling of Harmony, which comes from the Greek harmonia and means "agreement" or "concord"; in Greek myth Harmonia was the daughter of Aphrodite and Ares. The -i ending gives the word name a more personal look. In the United States Harmoni entered the top 1000 in 2015, peaked at number 702 in 2020 and sits at exactly number 1000 in 2025.
