Comprovisador is a real-time, networked system through which a conductor/composer mediates the interaction between a solo improviser and an ensemble of musicians who sight-read an animated score. The system uses multiple computers – one host and several clients – to perform algorithmic compositional procedures with the music material improvised by the soloist and to coordinate the ensemble’s response.
In general terms, Comprovisador is able to listen to an improvisation, decoding pitches, intervals and durations, and to facilitate the creation of different musical responses through algorithmic compositional procedures. Control of these procedures is performed in real-time, from a hardware terminal. The outcome of such procedures is displayed to players in the form of an animated musical score, viewed in computer screens. Through wireless connectivity, it is possible to place the computers – and, therefore, the musicians – apart from each other, allowing non-standard settings.
The described system – Comprovisador – is currently being developed by Pedro Louzeiro in his doctoral programme taking place in Évora University, Portugal, with the financial support of the Portuguese Foundation for Science and Technology (FCT) by means of a PhD Studentship.
