Visual Music surveys the rich and resonant relationship between abstraction, color, and sound over the past century. Follow its fascinating evolution from abstract painting through experimental film, and contemporary installation art in this major exhibition that brings together an international range of works by Wassily Kandinsky, Paul Klee, Oskar Fischinger, Jennifer Steinkamp, and others.

Brain-computer interface for music

The Future Music Lab at the University of Plymouth, England, is looking for new modes of interaction with musical systems through bio-signal interfacing, networks and responsive environments.

One of the projects the team is working on is a "brain cap" that can detect and recognize musical ideas in the minds of composers with up to 99 percent accuracy. Project leader Eduardo Reck Miranda reported up to 99 percent accuracy in recognizing specific electroencephalogram patterns for musical ideas using a 128-electrode EEG brain cap with signal-processing algorithms. [...]

Although the musical ideas tested were extremely simplistic, compared with the complexity of musical composition, the team has demonstrated that the idea of interfacing the brain with computers for musical applications is no longer a science fiction fantasy.

Miranda also plans to switch from the 128-electrode brain cap (rather cumbersome and inelegant) to a magnetic encephalogram, which records the magnetic field generated by neural activity. MEGs are less well-developed than EEGs, but they should provide more accurate, localized signals that might not even require a cap.

Regenerative Music explores new physiological interfaces for musical instruments. The overall goals of this project are to investigate the creation of ``Regenerative Music''. In Regenerative Music, the computer, instead of taking active only cues from the musician, reads physiological signals (heart beat, respiration, brain waves, etc..) from the musician/performer.

These signals are then used to alter the behaviour of the instrument itself. For instance filter settings on the sound can be applied, to which the musician responds by changing the way they play the instrument. The music will in turn generate an emotional response on the part of the musician/performer, and that this emotional response will be detectable by the computer, which then alters the behaviour of the instrument further in response.

DECONcert1

In DECONcert 1, we hooked up 48 people's EEG signals, which were collectively used to affect the audio environment. Signal averging was used across groups to clean the signal, and look for collective alpha synchronization (which occurs, for instance, when people close their eyes).

DECONcert utilized electroencephalogram (EEG) sensors which sensed electrical activity produced in the brains of the participants. 48 participants were equipped with EEG sensors, and the signals from the brains of the participants were used as signals to alter a computationally controlled soundscape. DECONcert allowed the particpants to form a feedback loop with the computational process of musical composition. The soundscape being generated generates a response from the participants, and the collective response from the group of participants is sensed by the computer, which then alters the music based upon this response. Again, the participants hear the music, and again respond, and again the computer senses and further alters the sound. In this way, collaborative biofeedback is being used in conjuction with an intelligent signal processing system to continually re--generate the music on the fly.
