Euphony, the aesthetic quality of harmonious and pleasing sound, has been a central topic in discussions of music, language, and literature. Authors such as Otto Jahn celebrated its "exuberant charm," comparing it to "dazzling colors of a glorious summer day," while George Santayana associated it with the "thrill of tonality" in song, observing its decline in modern speech.
Carl Engel stressed that euphony goes beyond simple consonance, demanding melodic form, and O. B. Boise underscored its emotional origins in joy and reverence. These viewpoints present euphony as both a technical standard and a channel for human emotion, connecting artistry with expression.
