Euphonious

What it means

Euphonious (German euphonisch) means pleasant-sounding. The word comes from Greek and designates a sound that is felt to be agreeable, smooth, and coherent in itself. Its counterpart is cacophony, discord. Both are judgments, not measurable properties — what counts as pleasant-sounding depends on time, style, and habit.

Musical use

An acoustic core can nevertheless be named: sonorities with simple frequency ratios produce fewer beats and are therefore felt to be calmer — octave, fifth, and third have always counted as consonant. But history shows how flexible the boundary is. The third, today the epitome of the pleasant sound, counted in the early Middle Ages as an imperfect consonance; the dominant seventh chord, once a dissonance requiring preparation, became a matter-of-course component of the cadence; sonorities that seemed harsh to the nineteenth century appear mild today.

Besides the sonority, further factors act: the register — the same chord sounds dull in a low register and clear in a middle one —, the distribution of the notes, the tone colour of the instruments, the intonation. A chord with unfavourably placed inner voices sounds murky although nothing is wrong with its composition.

Euphony is not an end in itself. Music lives from the alternation of tension and release; a consistently euphonious movement quickly seems bland. Dissonance is not what has failed, but what makes consonance audible as release in the first place.

The term is seldom used as a technical term but descriptively, for instance for a texture that avoids frictions or for a voice-leading that remains easy to sing. The counter-term is cacophonous. What is felt to be pleasant-sounding is not given by nature but depends on style, period, and listening habit.

Performance practice

In an ensemble, watch the spacing of chords: closely set low thirds almost always sound murky, and no intonation changes that. Tune sonorities by the beats instead of checking only your own note. And do not take dissonances back — they want to be audible so that the resolution works.
