Andrey Tarkovsky ’s 1972 sci - fi masterpieceSolarisis not just a heavy photographic film about outer space , it ’s an all - time great , period . Now , the score to the film isavailable for gratis download . And as awing and flighty vocalize as it is , the story of it ’s creation is arguably expert .
You see , the Solaris score was recorded on anANS synthesizer , which took source sound and engrave seeable sound waves on glass discs , and then use those same disc to reproduce the audio .
In this case the sine wave generated by the ANS are print onto five glass discs using a process which Murzin ( an optical locomotive engineer ) had to germinate himself . Each disc has 144 item-by-item tracks printed onto it , for a amount of 720 microtones ( distinct pitches ) , spanning 10 octaves . This yields a resolution of 1/72 octave ( 16.67 cents ) . The modulate light source from these wheels is then projected onto the back of the synthesiser ’s interface . These are arrange in a continuous swath vertically , with low absolute frequency at the bottom and high frequencies at the top .
The exploiter interface consists of a glass plate covered in non - drying unintelligible black mastic tree which be a drawing surface upon which the substance abuser makes St. Mark by scratching through the mastic , and therefore allow light to pass through at that point . In front of the glass plateful sits a vertical bank of twenty photocells which send sign to twenty amplifiers and bandpass filters , each with its own profit adapt control . It is akin to a ten - musical octave balance with two thickening per octave . The ANS is fully polyphonic and will return all 720 pitches simultaneously if required ( a vertical scratch would accomplish this ) .
While actual operation of this affair is somewhat knavish to wrap one ’s header around , the demonstration in the video shows what the affair looks like and offer a raspy idea of how it works . But mostly , it ’s just further proof that every facial expression of the film involve some wonderful , futurist idea behind it . Now go sit in a dark elbow room and listen to the soundtrack .
