Maker Culture and Artistic Creation: Developing a Device for the Electromagnetic Preparation of the Acoustic Piano
electromagnetic actuation; Maker; extended piano; music and tecnology
Falling within the theme of the expanded piano, this work presents an investigation into the electromagnetic actuation of the acoustic piano. In addition to surveying preexisting examples of this form of sound production for musical purposes—dating back to the late 19th century—it describes the development, within the scope of this project, of a prototype device that uses electromagnets positioned near the strings of a grand piano. Aiming to offer a simple and modular solution, the technical implementation was carried out through an immersion in Maker culture, using a microcontroller-based circuit board from the Arduino family, well-suited for self-directed learning. The Maker phenomenon, described as a contemporary branch of the do-it-yourself ethos, is discussed in its relationship to the creation of sound objects, digital lutherie, and artistic research. The work presents examples of an eight-channel actuator used in concert settings, as well as technological and musical byproducts that emerged from the research.
