One hundred and sixty two pieces of music, each one drawn by the law that moves a Wuyang orb. No hand touched the plates: the score goes in, the painting comes out.
A first printing is being proofed now — a 360 page square volume, hardcover, printed at the size the plates were drawn for. When preorder opens I will post it.
tell me when ↗Every mark on the cover is drawn by one of the three families of curve inside: a spiral a low key winds, a rose a high key opens, a Lissajous figure a middle key weaves.
Xuanwu Maxima is an instrument: it takes a piece of music and paints it, using the same mathematics that governs an orb thrown by Wuyang — where it launches from, how it curves, how long it is steered, where it comes to rest. Hold a note longer and its figure is drawn further. Play higher and it is drawn by a different family of curve.
This book is 162 pieces put through that law and printed. Bach, Chopin, Satie, Schumann, Debussy, Vivaldi, Tárrega and their centuries — each one a plate, each plate facing a page of its own numbers.
Nothing in it is random and nothing is timed by a clock. The instrument was run offline at a fixed sixtieth of a second, so a plate is a function of its score: the same piece will always draw the same painting, on any machine, forever.
Left: what the score is (6,151 notes, five octaves, 8:34 long, about twelve notes a second) and what the plate became (18.3% of the page inked, one connected body, balanced 48% down). Right: the painting those numbers describe. The note at the foot of the left page is written only from the measurements, so a reader can almost hear the piece before turning to it.
The instrument has three motions and seven pendants. Which section a piece landed in was decided by what the law had to say about it — its compass, its density, its repetition, its texture — not by taste.






Preorder is not open yet. A proof copy is at the printer; when it comes back and the edition is set, this page becomes the place to order it.
The instrument is playable in the panel beside this one — load any MIDI file and watch it paint. The written guide explains the law it obeys.
Scores are MIDI editions from the Mutopia Project, public domain, typeset by volunteers.
