cantilena

noun

1. A vocal melody or instrumental passage in a smooth, lyrical style.

   “He played a lazy tune that sinuated from C sharp down to G natural and back again. Astonishing that he could flute so lazy a cantilena while chasing nymphs.”

   “The sounds of insects, of which I am seldom conscious unless I have not heard them in some time, resumed, with a noise that reminded me of the tuning of the strings in the Blue Hall before the first cantilena began, a noise I sometimes used to listen to when I lay on my pallet near the open port of the apprentices' dormitory.”
