Trope, designed by ambient pioneer Brian Eno and musician / software designer Peter Chilvers, expands further on the ideas introduced by Bloom, their acclaimed iPhone application.  Darker in tone, Trope immerses users in endlessly evolving soundscapes created by tracing abstract shapes onto the screen, varying the tone with each movement.

Recommended for headphones and external speakers.

"Trope is a different emotional experience from Bloom - more introspective, more atmospheric. It shows that generative music, as one of the newest forms of sonema, can draw on a broad palette of moods." - Brian Eno

What's New in Version 1.2

Great (but)

I really love this app. It's a totally logical extension of Brian Eno's ambient music theories and methodologies for the 21st century.

In addition, I'm a lifelong insomniac and since I've been listening to this in bed, I've been falling asleep considerably faster than usual. (FWIW, I slept restlessly with it playing all night. The sleep timer came in handy.)

My one significant complaint though: I read about Trope in the iPhone edition of the music mag The Wire. However, when I try to open the magazine (in Newsstand) while Trope is playing in the background, the mag shuts down the instant after it opens. Trope is the only app that causes the mag to do this. If I could read The Wire and listen to Trope as I go to sleep, I'd be REALLY happy.


This is beauty ~ Brian Eno is genius for painting sound... Trope is my favorite of the Eno apps, and is the only reason I'm able to sleep most nights. I love it's Listen option and how you're able go set it to play for however long you'd like. (or let it run all night and see how it affects your dreams) It's simply mesmerizing, relaxing, and calms the mind. I recommend it for everyone.

Discreet Music, 35 Years Later


I enjoyed Eno's 1975 vinyl LP "Discreet Music" very much. It was created using a long tape loop between two reel-to-reel recorders with the erase head covered up. This is the same concept, 35 years later, and the whole thing fits in your pocket. It would be interesting to include a user sound input option. Maybe that will be included in the iPad version.
