Chicago Avenue Moon

About this app

Chicago Avenue Moon is a responsive, generative music app that gathers a set of variables including date, time, phase of the moon, and GPS location, and uses that data to determine how its music unfolds, in real-time. The piece is intended for a listener in motion, whose route and speed affect the composition. Composer Joshua Dumas wrote 1000 brief musical phrases which the app manipulates, sequences, and layers to create trillions and trillions of variations, a unique experience with every listen. He imagines the piece as a personalized soundtrack for strangers’ mundanities—an effort to help re-enchant a person’s daily commute, trip to the laundromat, or evening jog. The piece includes field recordings of his own walks around his neighborhood (Ukrainian Village in Chicago) in an attempt to bring his own experience of place in communication with others’, anywhere on earth. Though the piece grapples with permutations of impossible scale and explores how limited materials can give rise to grand complexities, it has humble beginnings. During the hottest weeks of the summer, while conceiving and composing, Dumas would open the door of the studio, and from the piano would watch the moon rise over Chicago Avenue. To escape the heat, he’d walk around his neighborhood, imagining this music, his revery disrupted and inspired by the sounds from the street. The app was developed in collaboration with Junecloud’s Mike Piontek, was recorded by Matt DeWine at Pieholden Suite Sound in Chicago, and was supported in part by an Individual Artists Program Grant from the City of Chicago Department of Cultural Affairs & Special Events and Illinois Arts Council, a state agency. Chicago Avenue Moon was performed by Josh Bell, Johnny Caluya, Kate Drown, Whitney Johnson, and Joshua Dumas, whose other projects include: Verma, Quarter Mile Thunder, Mar Caribe, Soundings, and Quiet Errors. Chicago Avenue Moon is a universal app available for iPhone, iPod touch, and iPad. A device with GPS is recommended, but not required—that includes any iPhone or an iPad with Cellular.

This update from Apple will improve the functionality of this app. No new features are included. - Chicago Avenue Moon is now available free of charge. If you enjoy the piece, you can tip the artist. - All device sizes and orientations are supported with a new adaptive design. - If the app is in the background and the volume is all the way down, it will now pause after a couple of minutes to conserve battery. - If location access is disabled, tapping "no location data" includes a button to open the settings. - Fixed a bug where the field recording track would not play on the first day of the month. - Fixed a bug where the elapsed time might be wrong if playback was paused in the background. - Fixed a bug where "no location data" might show incorrectly after being paused in the background. - iOS 8.3 or later is now required.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
