halldorophone

plural halldorophones

1. entertainmentAn electroacoustic string instrument, the sound of which makes use of electro acoustic feedback to produce drones and otherwise resembles a cello.

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

   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.

   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.

   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).
