InSitu/City: Paris – TACT

10/2021 Ircam – FR

In the framework of the InSitu/City activity in Paris (and surroundings), IRCAM is implementing the project TACT,  and specifically developing a device for the occasion:

TACT is a visual and sound work on a touch screen that proposes to the largest possible audience to become at the same time painter and composer, through a journey in the surrounding landscape.
Far from the postcard, TACT pursues a deep reflection on our relationship to landscapes. For this, the project relies on collaboration with different artists (composers and designers) who will propose their interpretation of the territory where the device will be located.

Conceived as an interactive composition environment, the device is intended to be invested by several composers. They propose to the visitors a sound, musical and evolving interpretation of the panorama. The main principles of the relationship between gesture, sound, and image are defined beforehand to ensure coherence, ergonomics, and fluidity of the interaction for the public, but the sound content and the audio-graphic effects are always able to evolve according to the proposals.

The composers integrate their instrumentarium in the device in order to create their own musical proposal. As an “open score”, each creation can be performed by its author and/or the public.

Conceived as an open work, TACT aims to give birth to a digital environment that allows the invited artists to create their own interpretation of the landscape. The gestures improvised on the touch screen by the public constitute the central means of expression of the experience. It is through these gestures that the participants  trigger the visual and sound metamorphosis of the device, making it, in turn, the instrument of their creation.

Conceived as an interactive device on a touch screen, TACT is installed on the 6th floor of the Centre Pompidou. After the spectacular ascent above the roofs of Paris, visitors are invited to live a second experience of the panorama, offered by the digital architecture of the device. Because of its situated nature, the project evolves according to the contexts of installation. Our proposal is therefore not intended to be implemented only at the Centre Pompidou; different interpretations could emerge in a second time
