In his work Contropasso (1998–9) Michelangelo Lupone
collaborates with Massimo Moricone in the dance showcase piegapiaga
achieving direct interaction between dancers and live electronics
performance. The choreography takes advantage of acoustic events as
generated by three dancers and further elaborated on via computer by the
composer through use of granular algorithms and digital filtering, allowing
the construction of the musical events to occur in real time. The live
electronics performer changes sound parameters in relation to the dancers'
movements by use of the program SDP – Sonorous Drawing Plane
(S. Lanzalone) – created specifically for the control of different
synthesis algorithms allowing them to be processed on systems such as
Fly30 (CRM) and Mars (IRIS). SDP reads and converts computer mouse data as
the operator creates lines corresponding to performance gestures, thus
creating both visible and audible output. This software allows a single
gesture to control more than one parameter, thus creating complex changes
in the audio programme output. The article deals with different
compositions, performances and didactic
situations the author has
experienced using SDP.
