"I have been experimenting with catalogues on diffeent materials beginning with my return academic environment in 2015, as an attempt of exploring the variety of notations from result-oriented scores to process-oriented game pieces. The idea was to notate the same piece or fragment in a graduaally changing diversity on this bipolar axis, and let the performers have a variety of approaches towards the score: they would either 
a.not know anything about it and look at it as free impro on graphic score
b.know that it is the same material but in can be arranged in different ways
c.know that it is the same piece but in can be read in different ways, changing only the interpretation.
What I am mostly interested in is how the different psychological approaches can create a red line at the level of the tensions, so that the passacaglia form can happen more at a tensional/emergetic level regardless of the precise material that is being played."
