Which term refers to a harmonious arrangement of words that is pleasing to hear?

The term that best describes a harmonious arrangement of words that is pleasing to hear is euphony. This concept is associated with smooth, melodious sounds created through the careful selection of words and sounds. Euphony often employs soft consonants and flowing vowels to create a rhythm and lyrical quality that appeals to the auditory senses.

In contrast, discord, cacophony, and dissonance refer to unpleasant, harsh, or jarring sounds, which evoke a sense of discomfort or harshness. These terms highlight sound arrangements that disrupt harmony rather than enhance it. Thus, euphony stands out as the concept that encapsulates the beauty and pleasantness of harmonious word arrangements.
