Concept is based on the assertion that audible sound has visual form. Nine basic tap dance sounds were recorded and symbol matrices were developed for each tap sound. Research participants were asked to choose which symbol most closely resembled each tap sound they listened to. A symbol set was determined from the results and used as the basis for the interactive rhythm poster design. People who interact with the poster are able to click on a series of sound buttons to play recordings of tap choreography that use the nine basic tap dance sounds. As the sounds play the user hears the rhythm, and can follow along visually to see it play out as well.
