HMM Bach by Moray Allan, Chris Williams, Daniel Winterstein and Joe Ruddy
Welcome to HMM Bach. This demo shows how a computer can actually create music. HMM Bach uses A.I. techniques to learn from existing music, then produce harmonisations to new music.


Demo #1: Jukebox

Play examples created by HMM Bach and compare them with the real thing. 		   
Demo #2: Jam Session

Compose your own tune, then have the computer create Bach-style harmonies for it.

Requirements: This demo requires Java (version 1.4+), a modern browser (use Mozilla Mozilla Firefox for best results, although Internet Explorer version 6+ will work), and suitable Midi-player software (e.g. Windows Media Player or Timidity for Linux). If you have problems running this demo, please try this alternative simpler version of demo #1.

There is a portable - and somewhat better - Linux-based version suitable for open-days, etc. Contact Diana Sisu for details.
