TweetDreams is a multimedia musical performance made from live Twitter data. During a performance tweets containing specific terms are retrieved from Twitter's servers, sonified into short melodies, and displayed graphically. The piece is created by three groups of users: the audience, the performers, and the world.
The audience is invited to tweet during performance with a special "local search term". Any tweets with this term are detected by our software and given special musical and graphical prominence.
The performers drive the software and shape the piece by selecting search terms and controlling various musical and graphical parameters.
The "global search terms" are used to bring in tweets from the rest of the world. During a performance, anyone tweeting anywhere in the world with one of these terms becomes a participant, and so TweetDreams becomes a public musical interaction that is simultaneously local and global.
How it works
How do we make music from tweets? We use the basic idea of association. Tweets which are similar get grouped into trees of related tweets, and are given similar melodies. Whenever a new tweet joins a tree it causes the previous tweets in that tree to also play their melodies, creating rippling textures of similar sound.
TweetDreams is implemented in three software components. A python application retrieves tweets from Twitter and calculates associations. Melodies are synthesized in ChucK. And graphics are rendered in Processing.
