Mastering of a Music City: DC Music Initiative

While Washington DC is home to a diverse and rich music and arts community, little attention has been directed toward cultural, music, and art grant allocations from the city government.

This study provides for the first time, an overview of the current state of grant allocations for the arts in Washington DC from 2013 - 2016, as well as an in depth look at the state of DC music grant allocations during the same time period. This study leverages datasets from the Washington DC open data portal.

Again (2015)

Storytelling doesn't always need words. Can repetition of video and visual themes matched to specific sounds carry the viewer through an "open-boxed" version of visual narration? Would it trigger similar responses in empathy for the viewer as well-written lyrics or a film would?

Created with Max MSP/Jitter. 40+ audio samples triggered live on a Novation Launchpad. Midi then feeds into Max MSP, triggers random objects which send bangs to jit windows and frame control messages.

The patch uses three video files, which contain compilations of 2-5 second clips. Frame control messages and a limited number of video files were used due to CPU constraints and pop-up/disappear effect of quicktime videos (instead of other approaches (eg. jit glue/scissors objects).

Sound Mapping (2017)

For anything out of sensory range, we perceive the distance between us and a location visually (eg. a map). In the Sound Mapping project, a user uploads two geospatial datasets: one with possible locations to 'stand' at, and the other, a set of locations anywhere in North America (in the image, a dataset of popular tourist locations and a dataset from DC's open data portal of 'places of worship' are uploaded). The Max patch then plays a sinusoidal wave depending on which entry is selected, with its panning, amplitude, and pitch modulating according to the distance and direction of any two given points. Based on the change in these variables from one location to another, the listener can perceive location and distance through its relative sonic placement to another location.    


Theo Goetemann is a mixed media artist and data scientist. His work frequently explores network and longitudinal data from open data sources and web scrapers. Theo is particularly interested in employing data-driven and narrative analysis techniques to examine online communities. His experience in this field includes research for the Georgetown School of Nursing and Health Studies, publications on American youth's consumption/participation in white nationalist/neo-Nazi online forums, and City78, an urban analytics organization which he co-founded in 2017 which develops data-driven, human-centric solutions for city governments, organizations and community leaders. As a supporter of open data, he regularly contributes datasets from his projects to His thesis for the Georgetown Government Honors Program examined the rapid expansion of national open data initiatives globally, which he defended in May 2017, receiving honors with distinction.

Theo's mixed media pieces deal with interaction with data through physical, three-dimensional spaces and auditory mediums, and are influenced by the idea of making data intuitive to the viewer. He is an active creator in the electroacoustic music and Max MSP worlds. His electroacoustic piece "Kill the Pianist" was performed at the 2015 Leonard Bernstein Festival of the Arts, and several of his Max MSP pieces have been featured in the BEAMS Electronic Music Marathon and CCT's annual Media Fest in Washington D.C. Theo is currently developing a project with The Ministry of Sound Nigeria to build a collaborative network of musicians and creators that extends past geographic boundaries.

Over the past five years, Theo has taught workshops on Ableton Live, Jitter (responsive visuals/video integration), and introduction to music production and technology courses. He speaks English fluently, Mandarin and Spanish conversationally, and is always working on his Korean.
