incremental repetition
a device used in poetry of the oral tradition, especially English and Scottish ballads, in which a line is repeated in a changed context or with minor changes in the repeated part. The device is illustrated in the following stanzas from the ballad "Lord Randal": "O where ha' you been, Lord Randal, my son? And where ha' you been, my handsome young man?""I ha' been at the greenwood; mother, mak my bed soon,For I'm wearied wi' huntin', and fain wad lie down.""And wha met ye there, Lord Randal, my son? And wha met you there, my handsome young man?"O I met wi' my true-love; mother, mak my bed soon,For I'm wearied wi' huntin', and fain wad lie down."
