As Stravinsky said, "There is no life without pulse, " but there's pulse and then there's The Rite of Spring's pulse!

NPR: Getting Hooked on the 'Rite' Sound

And so by the spring, the talks must show enough of a pulse to convince Congress that there is a deal worth sparing.

ECONOMIST: It is make-or-break time this spring for global trade talks

But this time, the spell is broken by the throbbing life pulse in the "Dance of the Adolescents, " signaling the start of spring.
