noun
roundelay
ROWN-duh-lay/ˈraʊndəˌleɪ/
A short lyrical composition with a repeated refrain.
The three singers repeat the refrain of a simple roundelay.

Etymology
Rondel meant “small circle” and named a poem whose opening couplet returned at the end. Its further diminutive gives roundelay the same image of words circling back through a repeated refrain.
