He saw that they were all working together at the first step of the species' break from the home world, and he understood that if the first step were taken successfully, with balance, they could run from star to star all across the night.
A great space opera but a second tier KSR novel.
Holywelkin was a brilliant physicist whose Ten Forms of Change unified relativity and quantum mechanics and allowed humankind to bring sunlight and 1g gravity -- and thus civilization -- to the far reaches of the Solar System. He also invented a strange musical instrument, the Holywelkin Orchestra, a one-man orchestra seen by many as nothing but a gimmick.
Johannes Wright is the ninth master of the Holywelkin Orchestra. He is the musical genius who will create the new paradigm of the age, one that doesn't just explain Holywelkin's new model of reality, but actually suggests there is a connection between our structure of thinking and the structure of reality itself. Because Wright has discovered the Holywelkin's ten equations map a little too neatly to the ten ways a composer can alter a piece of music for it to be a coincidence.
But Johannes Wright has enemies. As he travels downsystem on his great tour, he is attacked by a shadowy troupe of metadramatists, Actors whose theatre is real life. The troupe is composed of a member of the Orchestra's board of directors, a clan of Mercurian Mithraists and a former music school rival. They believe that their metaplay can determine Wright's destiny, and Wright's destiny will determine his music, and his music may very well determine reality...
And then there's Dent Ios, a rustic plutonian tapir farmer who reluctantly accepts his farming cooperative's request that he follow the tour and cover it for their literary music journal, Thistledown. If he'd just shown up for the co-op meeting he could've stayed home.
From anyone else, it would be an instant sci-fi masterpiece. But it's a little bit too neat. There's a bit too much of Arthur C Clarke's-sufficiently-advanced-science-looking-like-magic. I mean, the terras are cool, but they look like cheap Jack Kirby knock-offs when you compare them to KSR's terraformation of Mars, or his asteroid terrariums. The characters aren't much: one's a villain, one's Bilbo Baggins, and one's the next Bach. But then, this was his first novel (second to be published), and his writing about music (and his justification of writing about music) is interesting. The author hasn't quite found his voice, but you can see all of the elements for it are there.
