Tuning : The Living Scale & 432 Hz
Illuminance is the most expansive work of the catalogue : over an hour in a single span, without separate movements — a continuous orchestral flow, woven of motifs and symphonic mantras, advancing in one unbroken stream.
Where other works affirm a word, Illuminance opens a space. It is received over time : a crossing where time itself becomes matter. Composed by Yves Ruhlmann according to the principles of Trance Symphonic Music, tuned in The Living Scale and at 432 Hz, it addresses what is universal in whoever listens to it.
Where the rest of the corpus is made of pieces closed upon their own duration, Illuminance holds over more than an hour in a single span — the longest of the catalogue, in one stream, in one breath.
Its craft rests on this continuity. Motifs return and transform, symphonic mantras layer upon one another, the orchestra and the choir weave a fabric that continually thickens and lightens. The writing follows the symmetrical architecture proper to Trance Symphonic Music, tuned in The Living Scale and at 432 Hz, and extends it to an unprecedented scale : a single breath of an hour.
Like the other works, Illuminance also exists in its separate voices — strings, winds, percussion, choir — which let one hear, stratum by stratum, how this continuous edifice is built.
