Heartbeat. The contracting and relaxing of the main organ of the cardiovascular system. A pulse – expansions and contractions – that produces a particular rhythm. A rhythm that can be steady, uneven, slow, excited, calm, jerky. A variety of emotions can be gathered from a simple sequence of heartbeats.
Januš Aleš Luznar has been thinking about how to amplify the heartbeat and develop electronic music using only the sounds of the heart for years. In 2018, he started exploring the impact of manipulated sound on the functioning of the heart by using contact microphones and a special sound amplifier. Luznar treats the sound of the heart as a simultaneous instrument that plays on its own and never ceases to emit sounds. An instrument he can train, strengthen and control through different emotions, sound-mixing techniques and breathing.
Luznar calls his research series ictuscordis – the apex beat or the pulse felt at the point of maximum impulse. Based on audiovisual elements and the beating of the heart, the series is a dynamic manifestation of an intimate relationship between the audience and the collective heartbeat.
Listening to the sounds of the heart tells us about a person's physical health and potential cardiovascular problems; Luznar, however, uses these sounds to explore the relationship between the psychic and physical parts of the human body. By way of a biofeedback method, Luznar very precisely and in real time adds effects to the sounds of the heart, thus manipulating their intensity and taking the listeners on a journey through a variety of emotional states.
The result is an intimate, ambient immersion into the universe of the human heart.
The fourth part of the research series, memoriae draws on the past manifestations of the ictuscordis project: in the first part, Luznar amplified his heart (modulatio, 2018), in the second one (dialogue, 2019), his own and the dancer's, and in the last one, the hearts of people of different professional backgrounds (variatio, 2020).
The project ictuscordis is invariably performed live, with no pre-recorded samples.
