A presentation of the findings in a research project called Folk Song Lab. Folk Song Lab acts as a platform for improvising folk songs in a collective setting in sessions starting from the cognitive framework (Rosenberg, 2019) of ballads, lullabies, folk chorales, and herding songs. It also takes its starting point from B. H. Bronson and A. Lord, indicating that the song only exists in the act of singing. One question asked in the project is what new skills can be acquired with this approach. Another question is how to use different memory systems, system one or system two (Kahneman, 2013) when improvising lyrics and melodies. It explores the possibility of creating artistic methods for flow, using play, risk, mimicry, reorientation, feedback, and real-life situations based on the findings of psychologist Csikszentmihalyi (1990), to nudge the participant to end up in the flow channel, being able to create more freely. A Folk song lab session is about improvising folk songs in a collective setting. Group size can vary from 5 to 40 participants, and a session lasts at least 40 minutes. In the session, everybody contributes by improvising and listening, taking turns, or improvising simultaneously. https://folksonglab.com
