What does descant mean?
Descant is a word with two related faces: one musical, one rhetorical. In music, a descant is a melody set above the main tune — most often a high vocal line, such as a soaring soprano part woven over a familiar hymn or carol. It adds brilliance and ornament, and singers who take the descant are usually the most confident voices in the room. As a verb, to descant (usually with "on" or "upon") means to speak or write at length about a subject, sometimes admiringly and sometimes with a hint that the speaker is belaboring the point. The word entered English from Medieval Latin discantus, meaning a sound apart from the main song, sharing its root with "chant." Whether describing an angelic treble line or a colleague's extended lecture, descant lends any sentence a touch of erudition.
A melody or countermelody sung or played above the principal part of a composition, especially a high ornamental vocal line added to a plainsong, hymn, or carol.
"The trebles took up the descant in the final verse, sending the carol soaring above the congregation."
In British church music, singing "the descant" to a well-known hymn is a cherished tradition, typically reserved for final verses and festivals.
To talk or write at length about a subject; to discourse or comment extensively (usually followed by "on" or "upon").
"The lecturer descanted at length upon the decline of civic virtue in the Roman Republic."
This verb is formal and literary in register; when used of ordinary conversation it can subtly suggest that the speaker is verbose or self-important.
The plural is regular. It most often refers to multiple melodic lines in different pieces or arrangements rather than several lines within a single piece.
"The anthology includes descants for forty of the best-loved English hymns."
The next time someone drones on and on about their favorite subject, tell them they're 'descanting' — it's both an insult-proof compliment and a 600-year-old musical art form.

Etymology of descant
Descant comes from Medieval Latin discantus, formed from the prefix dis- (apart) and cantus (song), literally meaning "a sound apart from the song" — an apt description of a melody running alongside and above the principal part. The word passed through Old French as deschant before entering English in the medieval period. It shares its Latin root cantus with words like "chant," "incantation," and "accent," all descended ultimately from the Latin verb canere, "to sing."
How descant is actually used
The noun carries a positive, elevated connotation in musical contexts. The verb sense is somewhat formal and literary; when applied to speech it can carry a faint suggestion of tediousness, so use it carefully — praising a choir's descant is flattering, but saying a colleague descants on tax law may imply they go on too long.
