Last month, composer Tod Machover joined an online audience together with pianist Tae Kim in an experience that fused Web-based interaction with a live piano performance. This demo centered on the Cauldron app built at the Media Lab for the “Festival City” project commissioned by the Edinburgh International Festival. The app is populated with the sounds of the music most frequently performed over the history of the festival. The pieces are represented by colored circles, and participants online can “stir” the musical brew by positioning their cursors over the circles, which move and grow in response. During this live demo, Tod worked on a second interface to determine how the musical fragments would interact with one another, and piano virtuoso Tae Kim used the evolving images as a “score” to improvise music. His improvisations in turn will inform the final piece, which premieres on August 27th. Watch the demo in the video above.
