  • Elevated Pitch Socially Evolved Music John Reddin [email_address] Supervised By: Michael O’ Neill and Tony Brabazon Complex & Adaptive Systems Laboratory, UCD ODCSSS 2008 Online Dublin Computer Science Summer School
  • Motivation
    • Music Creation is a time consuming process
    • Music is difficult to create
    • Licensed music costs money to buy and to play in public (Performing Rights Society charges)
    • Creating music automatically is a challenge
    • Currently no such application freely available
  • Related Work: Generative Music Systems
    • Sounder (creates music visually, not free)
    • Noatikl (to give musicians ideas, not free, very basic)
    • fLOW (only ambient music, mac only, not free, very basic)
    • MusiGenesis (windows only, not free, cumbersome)
    • Koan (no longer available)

  • Problem Statement
    • Although research has been carried out, there is currently no freely available application of grammatical evolution to evolve western music
    • This has never been done in a social context with computers as the objective and groups as the subjective
    • Music is inherently social and this should be explored

  • Background Research
    • Evolutionary Algorithms
    • Grammatical Evolution (GE)
    • Music Theory, MIDI processing
    • GEVA (Grammatical Evolution in Java)
    • JFugue (Music Programming in Java)
  • Research Methods
    • Reading published papers on GE, evolutionary algorithms, music generation.
    • Reading lecture slides on aforementioned topics.
    • Speaking to experts in the area and with the creators of GEVA.
    • Rapid prototyping and modular design.
    • Testing of MIDI libraries.
  • System Model GEVA Grammar Music Generator Fitness Function User Feedback Playback/Save/Upload/Discard Online Database
  • Demo & Screenshots “ Studies have shown music at work improves productivity performance. It is estimated that more than half a million businesses across the UK are playing music illegally. “ http://www.bodytonicmusic.com
