The adjective “dulcet” is used for sounds that are melodious, soothing, and often soft or delicate. In poetry, it can create an atmosphere of beauty and harmony, though it does not necessarily mean completely quiet. In William Watson’s “The Key-Board,” “dulcet” contrasts with “thunder” to describe the keyboard’s range of sweet and powerful musical sounds.

“Dulcet” comes from the Latin dulcis, meaning “sweet,” through Old French. It most often modifies sounds, voices, music, tones, or sometimes speech. The word commonly suggests sweetness and pleasing quality, but it can also imply gentleness or softness. In Watson’s poem, “dulcet” is part of a contrasting pair with “throats of thunder,” emphasizing the keyboard’s ability to produce both powerful and delicate music. Related terms include “melodious,” “sonorous,” “harmonious,” and “mellifluous.” “Harsh,” “discordant,” and “cacophonous” are contrasting terms.
