Sonar data was captured at important locations in Duke Ellington's evolution in Washington, DC.
The color, patterns, and rhythms are determined by the distance of people from the machine.



The machine translates the rhythms of the street into musical tones.

In commemoration of the 100-year anniversary of Duke Ellington's first song,
Soda Fountain Rag, written on the 2000 block of Georgia Avenue NW.


 Realtime translations of sonar data to sound and image continued in the Hamiltonian Gallery.

 Five Variations of the Soda Fountain Rag by Duke Ellington

In the summer of 1914, Duke Ellington was working as a soda jerk in the Poodle Dog Cafe.
One day, the cafe’s pianist became too drunk to play and Duke was subbed in. He sat down at the piano
and improvised a number that emulated the rhythms of the soda fountain machine.
