Feedtank: Jonah Warren & Steven Sanborn


Transpose is an audiovisual performance instrument. Transpose takes a user’s physical actions captured from a video camera and translates them into sound and color in real time. It allows users to use free gesture and movement to create sound and compose songs. In Transpose, the user is presented with projected noteboxes, or colored rectangles that produce sound. By using their silhouette to overlap these noteboxes, the user can create tones. The higher the user’s silhouette is positioned in the notebox, the higher the tone. The lower their silhouette is positioned, the lower the tone. Also, the more a user’s silhouette overlaps the noteboxes, the louder the tone. Transpose was initially created to address the absence of physical human expression in many electronic performances. Although the use of computers in music-making has brought new potential for experimentation and sound creation, it has often been at the expense of live performance. All too often the improvisation and spontaneous decisions of electronic performers are hidden behind a laptop screen, invisible to the audience. Transpose attempts to change this dynamics by accentuating the performer’s actions and improvisations, rather than hiding them.
