Kjetil Falkenberg Hansen - The techniques of scratching

Wednesday, December 10th, 2008

Kjetil comes from the KTH Computer Science and Communication where he is a PhD researcher. He burns for scratching and loves the sound but after practicing for an hour he decided that he was no longer interested in learning to scratch. His interests are in scratch analysis and interface design. He shows us a fascinating video of his own practice which centres on the designing interfaces for new scratch style music.

Kjetil outlined the mix of old and new technology that makes up turntablism. He claims that hip-hop has demanded a new form of instrument that is now concerned not just with rhythm but also melody. On the topic of the turntable metaphor, differing from Taku he does not believe in the rotating disc metaphor for media playback. He believes that scratching has reached a turning point in popularity after its high in the 90s.

This was reflected by the large amount of speakers and the range of subjects they covered. Because of this, and the enthusiasm of the speakers, the session ran far beyond the allotted time range.

Robin Price - Visualization software

Tuesday, December 9th, 2008

Robin presents a performance/installation piece which maps a visualization from a live radio input database, created in real time. The input is simply the radio dial, and whenever there’s a change to the dial, the system automatically makes a new ‘entry’ (sample) in the database.

He also presents a description of the mapping strategy for the motion graphics element

  • X position proportional to loudness
  • angle theta proportional to brightness
  • radial distance from axis proportional to noisiness
  • Mode selector simply permeates the mapping between polar co-ordinate and the three spectral features
