Hati Hati - Participatory Installation

A participatory installation in which the audience is invited to engage with one another by paying attention to one another's cardiac response, mediated by/through a closed system of HRV finger sensors and speakers. The data obtained from participants' pulses is used live to compose soundscapes derived from a single sampled harp note, which is triggered repeatedly in distinct ways according to the cardiac changes of the participants. "Please be seated... Using sensors to read your pulses, your hearts will play the harp. This harp is tuned to slendro, one of the main laras (scales) in Balinese and Javanese Gamelan. Unlike a traditional western pentatonic scale, the five notes of slendro are almost evenly distributed in pitch within the bounds of a western octave; as such, slendro differs in tonality to western music. In Indonesian your heart is hati; hati hati is also used as an imperative expression, meaning ‘be careful’."
