This English term describes the sixteen-line form which is known in French as the chanson. The form usually begins with a four-line refrain ABAB which is followed by two further lines bc and the first two lines of the refrain AB. There are then four more lines abba, followed by the repetition of all four lines of the refrain ABAB. Lydgate uses this French chanson form for the roundel in his version of Henry VI’s Triumphal Entry into London and for a roundel in celebration of Henry VI’s coronation, and Charles d’Orleans writes English lyrics in this form which he calls ‘rundell’ in his English writing and chanson in his French autograph manuscript. Hoccleve, however, uses the term to refer to poems in the form of a rondeau tercet, also calling this form a ‘cha(u)nceon’.
