halldorophone

English

Etymology

Named according to the inventor, Halldór Úlfarsson from Iceland, who developed the instrument in late 2000s while studying at University of Art and Design Helsinki.

Noun

halldorophone (plural halldorophones)

1. (music) An electroacoustic string instrument, the sound of which makes use of electro acoustic feedback to produce drones and otherwise resembles a cello.
   • 2016, Alice Eldridge, Chris Kiefer, “Continua: a resonator-feedback-cello duet for live coder and cellist”, in Proceedings of the Fourth Conference on Computation, Communication, Aesthetics and X, page 399:

     Continua is a duet for cellist and live coder, each playing a hybrid instrument based on the Halldorophone, an electroacoustic instrument in which electromagnetically-controlled feedback can be induced independently on each string.

   • 2017, Alice Eldridge, Chris Kiefer, “The self-resonating feedback cello: interfacing gestural and generative processes in improvised performance”, in Proceedings of New Interfaces for Musical Expression:

     Following the design of the halldorophone, the self-resonating behaviour of the Feedback Cello is induced by acoustic and vibrational actuation: the signals from pickups under each string are sent to a speaker built into the back of the instrument, and a vibrational transducer fixed on the front.

   • 2018, Andrew Hugill, The Digital Musician, Routledge, →ISBN:

     One recent example is the 'Halldorophone', a range of adapted string instruments built by Halldór Úlfarsson that combine acoustic, electronic and digital functions within a single instrument (Figure 8.3).

   • 2018, Halldór Úlfarsson, “The halldorophone: The ongoing innovation of a cello-like drone instrument”, in Proceedings of New Interfaces for Musical Expression:

     After ten years of use, the halldorophone has a growing repertoire of works by prominent composers and performers.

   • 2018, Thanos Polymeneas Liontiris, “Low Frequency Feedback Drones: A non-invasive augmentation of the double bass”, in Proceedings of New Interfaces for Musical Expression:

     Influential works were the Overtone Fiddle [3], the Self-Resonating Feedback Cello [4, 5], the feral cello [6], the Magnetic Resonating Piano [7], the Feedback Resonance Guitar [2], Half-Closed loop [8] as well as the ongoing work of Halldór Úlfarsson, halldorophone[9] a cello-like feedback instrument.
