Thanks to Sebastiaan Smink for being an absolute lifesaver for this project; without him, the performance would not have happened. Thanks to Kunstruimte Het Langhuis for providing their space for the residency week and the performances, and to Thijn Kolk (and the rest of the team) for their hospitality. Thanks to Stichting de Zaaier for partially funding this project, and to Kathryn Cok for submitting my project plan to them. Thanks to my research supervisor Andrew Wright for keeping my thoughts critical and helping me with shaping this research to where it is now (and the most welcome coffees). Thanks to my master circle leader Loes Rusch and the rest of the master circle group for sharing their opinions, answering questions, and having fruitful discussions (and laughs). Thanks to Ilja Middendorp, Eduardo Gaspar Polo Baader, and Sybren Holwerda for reading and providing feedback on my final research. Thanks to Heloisa Amaral and Renee Jonker for their fantastic master electives, which have inspired parts of this research, but foremost, have shaped me as a musician, artist, and human. Thanks to all the people who have provided me with their stuff, help, or time to make the performance or residency week happen: José, Florian, Rémi, Sander, Bouke, Aart, Nino, and Martijn. Thanks to Eric van der Hoeven from ‘t Speeltuygh in Zwolle for sharing his knowledge on microphones with me. Thanks to my dad who helped me with fixing and soldering the LED strips the day before the performance. Thanks to Anaïs Saebu, Koen Gardebroek, Hendrik Behnen, and Pauric Freeman for their help on (the video of) the performance. Thanks to all the (60-80!) audience members for visiting and sharing their thoughts. Thanks to Gijs van der Heijden for brainstorming with me on a possible new piece inspired by the harp sonata. Thanks to library Stadkamer Zwolle for providing good coffee and a great place to work. Thanks to everyone who has in any way provided me with their thoughts, patience, or help during the writing of this research.
