Data Mining / Live Scoring is a project for an algorithmic composition for a six-member acoustic ensemble aided by a computer. This performance is based on Twitter, where tweets are being downloaded and analyzed during the performance. The analysis of the tweets determines various parameters of the algorithmic composition which is being carried out in parts during the show. The resulting scores are being projected on screens for the ensemble members to sight read. The score projection includes a blinking cursor controlled by the main computer which facilitates coordination between the performers and highlights the bar currently being played. The performance is accompanied by a light installation part of which is used to communicate the sentiment of the score to the musicians.
