I divided these 2 years of this academic research into 4 phases where I would dedicate most of my time working on each of them:  Instrument design,  Interface,  Production  and Documentation.

I worked with a team of freelancers and each prototype was weekly updated into the project webpage. In these reports we classified our improvements by writing: Solved + New issues + Future considerations. Those reports can be found at the following website [11]. The project was developed and produced at the instrument inventors initiative and involved few partners to be accomplished. At this thesis I will be writing a compilation of some of them: their process, results and future reflections.

Realizing that Knurl isn’t only an instrument, but also an interface, a platform and part of a hardware, I took a lot of time to design each prototype and test its application of the interface, electronics, design format and references having a specific music project as an outcome. I also learned to prioritize what was essential for the way I produce music in the current context by narrowing this research results into these testing cycles. This experience is described further in chapter 'Designing’ of this document.

When testing those prototypes, playing my instrument became a laboratory to solve technical challenges or find discoveries of this research. I organize those practices into subchapters, combining with each research area of this research (Design , 3D Printing, Interface, Performance and Composition). They are presented in the chapter ‘Playing’. The performances described in this thesis were presented in the course of the academic year at international and national music productions, such as: Gaudeamus, Theater Carré, Amare, Chigiana music festival, Morphine music festival and so on.
