This article describes a performance of a clarinet augmented by new media art, as well as its technical and conceptual design. MAD Clarinet 2.1. is a sound and visual journey made through an installation/performance, which offers to the audience a sensorial experience conducted by a panoply of (un)recognizable sounds. The performance is realized by a clarinetist, who, using his traditional instrument, physically places himself in predefined positions in order to interact with the digital component of the installation. In turn, this digital component acts through a set of motion sensors and sound capture. These two processes, besides triggering the computational digital sound component which works in a duet with the instrumentalist, and also triggering an acoustic augmentation of the clarinet ́s possibilities, namely delay and reverb, allow the sound captured from the performance to serve as a parameter for the creation of generative computational visual art, which develops in real-time throughout the performance. In short, this work uses the connection between the instrumentalist of a traditional instrument with the new media art, in an extrapolation of what would be expected from a musical instrumental performance. This work was developed by Rui Travasso and Luís Marques.
