Leon Senger"Space of Improvisation" is a set of cards that musicians can use to find new ways of improvising together or at least to raise more awarness on ways they use sounds to interact. The cards are based on a concept around conceptual metaphors and use insights from cognitive linguistics into how we perceive of the world and our actions in metaphoric ways. You will find metaphoric instructions on which kind of sounds to play, on how to behave towards other players and more compound metaphorical instructions on how a improvised piece can be structured.
