A lot of experimenting with improvising lyrics is done in the folk song lab sessions. We try to use the formulas inherited in the ballad form, such as rhyme, repetition and certain expressions etc. This session we did use two methods for improvising: end-rhymes and ‘crochet/braid /chain-singing’ meaning that we repeat the subject / word/ rhyme from the last verse at least for two or three verses. This reflects the way the old ballads are created. It’s a strong rhetoric practice that is useful when improvising as well.
