Harmony
Harmony is the pleasing arrangement of combined, simultaneous musical notes structured according to the composition and progression of chords. With harmony, superposition of sounds are orchestrated into congruent parts. Harmony is the playing together of interacting different notes, delivering rich and colorful music.
In opera, the libretto is the words or lyrics, as distinct from the music.
Denotation means the primary meaning of a word.
I hope this helps! :)
