和声|わせいwasei[1]atamadaka (head-high)

1. no-adjective, musicharmony; concord; consonance

• SynonymハーモニーNeutralEveryday loanword for harmony in music and general concord; also figuratively for people getting along. Broader in use than 「和声」.
• Related諧調かいちょうWrittenWritten and rare; stresses the pleasing harmony of sounds or colors. Also used for color tones in art.
• Related音楽的調和WrittenWritten phrase for harmony in music; broadly describes sounds combining well, but is not the music-theory term that 「和声」 is.
• Antonym不協和音ふきょうわおんNeutralSounds played together that clash and grate; the opposite of the harmony 「和声」 seeks. In music theory it is also part of harmonic treatment, and can mean human discord.

Use 「和声」 for harmony in music theory, as in 「和声学」. In everyday talk say 「ハーモニー」, which also covers people working well together. 「不協和音」 is the opposite: harsh, clashing sound. 「諧調」 and 「音楽的調和」 are written-style words for well-blended sound.
