It’s important that you grant the location request “Allow While In Use” or “Always Allow”, when prompted.
3. Place phone in a pocket, wear headphones and go outdoors. Since the technology relies on GPS (satellite) coverage, you’ll need to be outside for the app to work.

Holon is an auditory AR app for city-wide, ubiquitous, interactive music that is driven by the activity of listeners and their interactions with the environment. Holon can measure proximity to amenities, such as benches, bins, post boxes, shops, cafes and so on, effectively turning them into musical emitters and modulators.
Requirements are an iPhone and a data plan (amount of data is low). Headphones or in-vehicle audio are needed for perceptual feedback (AirPods Pro recommended with transparency mode).
Holon works best when used passively, by placing the phone in a pocket. This helps the software to detect coupled body movements. The tempo of the music is synchronised to your step rate (this may take 10 seconds of continuous walking to be calculated).
Musical sequences and events are created from geospatial data and environmental data in real time. Directions, time of day and the position of the Sun/Moon all influence the music in various ways. For example, cloud cover can determine the musical scale, while activity/speed might trigger notes.
Holon is built on the Holonic platform for geospatial musical computing and available as a whitelabel solution for B2B clients. We can now provide a limited number of artists early access to our content tools on request.
