  This paper describes a system designed as part of an interactive VR opera,
which immerses a real-time composer and an audience (via a network) in the
historical location of Gobeklitepe, in southern Turkey during an imaginary
scenario set in the Pre-Pottery Neolithic period (8500-5500 BCE), viewed by
some to be the earliest example of a temple, or observatory. In this scene
music is generated, where the harmonic material is determined based on
observations of light variation from pulsating stars, that would have
theoretically been overhead on the 1st of October 8000 BC at 23:00 and animal
calls based on the reliefs in the temple. Based on the observations of the
stars V465 Per, HD 217860, 16 Lac, BG CVn and KIC 6382916, frequency
collections were derived and applied to the generation of musical sound and
notation sequences within a custom VR environment using a novel method
incorporating spectralist techniques. Parameters controlling this 'resynthesis'
can be manipulated by the performer using a Leap Motion controller and Oculus
Rift HMD, yielding both sonic and visual results in the environment. The final
opera is to be viewed via Google Cardboard and delivered over the Internet.
This entire process aims to pose questions about real-time composition through
time distortion and invoke a sense of wonder and meaningfulness through a
ritualistic experience.
