Building on previous&lt;br&gt;research, we employ a hybrid musical instrument: Phonodeon&lt;br&gt;(Georgaki et al. 2005), consisting of a MIDI-accordeon coupled to&lt;br&gt;a real-time algorithmic interaction and vocal synthesis engine.&lt;br&gt;The synthesis is based on data provided by the AOIDOS program&lt;br&gt;developed in the Department of the Computer science of the&lt;br&gt;University of Athens, investigating Greek liturgical chant&lt;br&gt;compared to bel canto singing. Phonodeon controls expressive&lt;br&gt;vocal synthesis models based on formant synthesis and&lt;br&gt;concatenated filtered samples. Its bellows serve as hardware&lt;br&gt;control device that is physically analogous to the human breathing&lt;br&gt;mechanism [georgaki, 1998a], while the buttons of the right hand&lt;br&gt;can serve multiple functions. This paper focuses on a particular&lt;br&gt;aspect of control, namely that of playing in the traditional nontempered&lt;br&gt;and flexible interval structure of Greek modes (ήχοι:&lt;br&gt;echoi) while using the 12-semitone piano-type keyboard of the&lt;br&gt;left hand. This enables the musical exploration of the relationship&lt;br&gt;between the spectral structure of the vocal timbre of Greek chant&lt;br&gt;and characteristic intervals occuring in the modal structure of the&lt;br&gt;chant. To implement that, we developed techniques for&lt;br&gt;superimposing interval patterns of the modes on the keyboard of&lt;br&gt;the phonodeon. The work is the first comprehensive interactive&lt;br&gt;model of antique, medieval and modern near-eastern tunings. The&lt;br&gt;techniques developed can be combined with techniques for other&lt;br&gt;control aspects, such as timbre and vocal expression control,&lt;br&gt;phoneme or (expressive/ornamental/melodic pattern, inflection)&lt;br&gt;sequence recall and combination, data record on/off, or others,&lt;br&gt;which form part of the phonodeon project. This research can find&lt;br&gt;applications in many computer music fields such as&lt;br&gt;algorithmically controlled improvisation, microtonal music, music&lt;br&gt;theory and notation of (algorithmic/computerized) real-time&lt;br&gt;performance, and computer modeling of experimental or nonwestern&lt;br&gt;musical styles.</style></abstract></record></records></xml>
