An experimental audiovisual concert which visualises sound, and  
targets people interested in improvisation, audiovisual media, and  
more specifically, people with hearing difficulties. Curated by  
Adinda van ‘t Klooster.

Date: 17th of October
Time: 7:30 pm
Venue: The Sage Gateshead, Barbour Room
Tickets: £5 Concessions: £3
Box Office: 0191 443 4661

For this concert at The Sage Gateshead visual artist van ‘t Klooster,  
asked a group of musicians from different backgrounds to improvise to  
a range of visual scores rather than notated ones. The sound/music  
thus created is then visualised in a live spectrogram, especially  
commissioned for this performance. The spectrogram is responsive to  
different instruments, such as the brass instruments, voice and  
piano, shown by three different spectrograms which are overlapped in  
one image.

A spectrogram visualises all the simultaneous frequencies that are  
present in a sound. Much used in auditory neuroscience, the  
spectrogram shows pronounced patterns of the voice and is widely  
regarded as the most revealing visual display of speech. Speech  
therapists can read voice spectrograms much like musicians read notes  
and they use the spectrogram in teaching deaf people how to use their  

The spectrogram software was written especially for this performance  
by Matt Green who is currently undertaking a PhD at the Sonic Arts  
Research Centre in Belfast. The interface allows for a high level of  
frequency adjustment/customisation in the sound with a direct visual  
and aural output. Thus, the program is an ideal tool for people with  
hearing difficulties as it allows for a better understanding of which  
frequencies in the sound they have lost or are over-sensitive to.

After the concert there will be the opportunity to try out the  
spectrogram software which allows you to amplify or take out  
particular frequencies with direct audiovisual feedback.

An induction hearing loop will be available at the concert venue.
The proceeds of this concert will go to the Royal National Institute  
for the Deaf.

Translating Nature: B) Nanotextures
8 mins by Julie Freeman

Freeman's animated visual score is an abstracted representation of a  
biological process. The process is derived from research into self-  
assembled nano-textures that could be used for stem cell sorting and  
the detection of pathogens. The score has been created in Processing,  
a java-based programming environment.
With many thanks to Jeremy J Ramsden, Professor of Nanotechnology at  
Cranfield University.

30 mins by Adinda van ‘t Klooster

This half hour visual video score on DVD was initially generated by a  
computer program written in Max/MSP. The patch was designed to  
respond to the live sound input of ‘Sarah was Ninety Years Old’ by  
Arvo Pärt, performed in Gloucester Cathedral. The video score thus  
created has since been given to various electro acoustic musicians  
who have improvised to it in different ways. This is the tenth  
interpretation of the score.

This score was built in second life by creating virtual kinetic  
sculptures occluded by infinite dark matter (0, 0, 0). It was  
recorded live as a single performance by Parthenon Acropolis (Brown’s  
avatar) mapping the shapes and colours onto discrete elements of the  
music he was listening to.

Smith enjoys breathing new life into sad and lonely forgotten  
machines. For this score he has stripped a Nintendo NES cartridge  
back to a basic set of tiles. Each tile set responds to a MIDI* note  
number. By passing it live MIDI information he has been able to  
create a dense visual score that is nostalgic, hypnotic and  

This score has rapid flashing lights so photo sensitive epilepsy  
warnings apply!

* MIDI stands for Musical Instrument Digital Interface and is an  
exchange data format used between a computer and musical instruments.
