Summary

The application relates to a system for automatically generating a musical composition, where a user can input a briefing narrative, or description of how the emotional impact of the music should change over time, and the system outputs a piece of music fitting the brief. The building blocks of this process are so-called “form atoms”: data structures encapsulating the essence of snippets of music, and rules that allow the music to be varied within the theme and appropriately concatenated with variations in other form atoms to build a piece of coherent music that fits the narrative.

The Hearing Officer considered various arguments made at the hearing advocating that the invention was technical and lay outside the excluded categories. However, considering substance over form, and in light of the contribution, the invention was found to be excluded as a program for a computer as such.
