Entangled Hyperspheres
As if the name was predestined, this was premiered simultaneously in Buenos Aires and Paris during the show “Virtuality” in 2021. The microtonal performed music is composed purposefully : Entangled Chorus
For music in ¼th tone, the initial method, imagined by Ivan Wyschnegradsky for two pianos can be adapted for two orchestra:
- Orchestra A is tuned at 440Hz and plays the 12 usual notes (do, do#,…)
- Orchestra B is tuned at 440Hz - ¼th tone (427.7 Hz), and plays the 12 additional notes (do+ do#+,…) .
Created with S.de Gérando to model 24tones music, two Planet-4D models are entangled: A corresponds to our scale, B to our scale detuned by 1/4 tone.
We end up with two sets of 12 quaternions sharing the same origin, The global rotation of the system is done according to the spherical barycenter of active notes among the 24 available
As in Planet 4-D, the user freely moves and rotate the spheres, he can select the tones of A/B or both.
The animated score is displayed while the demo song playing
