  1. 1. 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
  2. 2. Motivation <ul><li>Music Creation is a time consuming process </li></ul><ul><li>Music is difficult to create </li></ul><ul><li>Licensed music costs money to buy and to play in public (Performing Rights Society charges) </li></ul><ul><li>Creating music automatically is a challenge </li></ul><ul><li>Currently no such application freely available </li></ul>
  3. 3. Related Work: Generative Music Systems <ul><li>Sounder (creates music visually, not free) </li></ul><ul><li>Noatikl (to give musicians ideas, not free, very basic) </li></ul><ul><li>fLOW (only ambient music, mac only, not free, very basic) </li></ul><ul><li>MusiGenesis (windows only, not free, cumbersome) </li></ul><ul><li>Koan (no longer available) </li></ul>
  4. 4. Problem Statement <ul><li>Although research has been carried out, there is currently no freely available application of grammatical evolution to evolve western music </li></ul><ul><li>This has never been done in a social context with computers as the objective and groups as the subjective </li></ul><ul><li>Music is inherently social and this should be explored </li></ul>
  5. 5. Background Research <ul><li>Evolutionary Algorithms </li></ul><ul><li>Grammatical Evolution (GE) </li></ul><ul><li>Music Theory, MIDI processing </li></ul><ul><li>GEVA (Grammatical Evolution in Java) </li></ul><ul><li>JFugue (Music Programming in Java) </li></ul>
  6. 6. Research Methods <ul><li>Reading published papers on GE, evolutionary algorithms, music generation. </li></ul><ul><li>Reading lecture slides on aforementioned topics. </li></ul><ul><li>Speaking to experts in the area and with the creators of GEVA. </li></ul><ul><li>Rapid prototyping and modular design. </li></ul><ul><li>Testing of MIDI libraries. </li></ul>
