Actions that are left open as 'undefined' are probably collective tacit knowledge, that is also dependent on culture. The personal 'merging' twist from which this outcome results might be strong tacit knowledge. Personal Tacit Knowledge.
The initial idea/starting point:
I think the origin of the initial idea/starting point can be explained best by the term 'field of interest'. I think it is like searching with a string of people for traces within a certain enclosed area. The mind will go along all the points (coordinates) in this coordinate system continually. Although, as described above, this might seem calculable, the axes should be imagined flexible, hybrid, and fluid, transparent and multi-dimensional. This metaphorical elaboration is just to 'sketch a curve' of how a thought can 'run' and come into being. This description is quite comparable to a description composer and director Julian Klein has used, but then as mode of aesthetic experience. He describes this perceptual mode as that of 'sensible interfering frames’.
This personal knowledge relates to the singular factor that could be enacted in an artistic research project.Writing on the actions of the ‘MASTER’ that are still unknown or not known yet, might become the ones that ‘invite’ to produce tacit knowledge. These actions should not be seen as ‘genius’ actions in itself. These actions are part of a construction, a set up in a context, namely: the set up of an artistic research.
