This research explores the augmentation of the bandoneon, an iconic Argentine instrument traditionally associated with tango music, through the integration of live electronics and extended performance techniques. The research delves into the development of a unique system that enables real-time interaction between the performer and the electronics, transforming the bandoneon into a dynamic and expressive instrument. The study investigates the implications of this augmented approach on musical expression, embodiment, and the relationship between the performer and the instrument. Through a series of performances, including collaborations with other musicians and participation in festivals, the thesis examines the practical application and reception of the augmented bandoneon in diverse contexts. The findings contribute to the discourse on the intersection of traditional instruments, technology, and contemporary musical practices, offering insights into the possibilities and challenges of augmenting a culturally significant instrument like the bandoneon.
