Porto: Universidade9789897461705http://hdl.handle.net/10400.14/27563This paper discusses the development of HASGS regarding augmentation procedures applied to an acoustic instrument. This development has been driven by the compositional aspects of the original music created in specific for this instrumental electronic augmented system. Instruments are characterized not only by their sound and acoustical properties but also by their performative interface and repertoire. This last aspect has the potential to establish a practice among performers at the same time as creating the ideal of community contributing to the past, present and future of that instrument. Augmenting an acoustic instrument places some limitations on the designer ́s palette of feasible gestures because of those intrinsic performance gestures, and the existing mechanical interface, which have been developed over years, sometimes, centuries of acoustic practice. We conclude that acoustic instruments and digital technology, are able to influence and interact mutually creating Augmented Performance environments based on the aesthetics and intentions of repertoire being developed.engSaxophoneAugmented instrumentsGestural interactionLive electronicsconference object
