My research and art practice can be found at helencollard.net

The performance work below uses a neuroimaging technology called fNIRS whilst performing breathing exercises - pranayamas. In these exercises the breathing is controlled, whilst  the hemodynamic response is sonified in real-time allowing the audience to experience the effects of the pranayama performance on changing hemoglobin levels in an audio form. Two videos show two versions of the sonification the second showing some of the coding process to translate the fNIRS data into sound. The images at the bottom of the page show the graph data gathered from two pranayama practices showing the marked changes in levels for each pranayama exercise. Finally the last image shows the scoring process of using the pranayama practice to improvise on Alice Coltrane’s improvisation.
