Neurocórdio is an interactive string installation whose interface is via a brainwave reader that makes it possible to produce music based on the user's ability to concentrate.
It consists of 10 infinite monochords, a brainwave reader and a control module. When interacting with the work, by blinking your eyes you can select each of the monochords. When you reach a certain level of concentration, the selected monochord is activated. By controlling the blinking of the eyes and the state of concentration, you can switch various monochords on and off, creating different sound combinations. When concentration is lost, all the monochords are deactivated simultaneously.
In this piece, it's interesting that as the piece is activated, a favourable state of concentration is produced, creating feedback. The more the participant concentrates, the more music is produced and the more music is produced, the more the participant is able to concentrate, producing more music.
