Venturi Effect
Summary
An instrumental of 2:17. The Venturi effect describes the drop in fluid pressure that occurs when a fluid flows through a constriction — the narrowing accelerates the flow and reduces pressure, a counterintuitive result that underlies carburettors, atomisers, and wing lift. As a title it suggests something that gains speed and intensity through constraint rather than despite it.

Detail
The Venturi effect was described by Giovanni Battista Venturi in 1797 and has been applied wherever fluids — including air — need to be accelerated, mixed, or measured. The counterintuitive relationship between constriction and acceleration makes it a useful metaphor for creative or political processes: constraint as the condition of velocity rather than its obstacle.
In the context of the SOTD sequence, arriving after the expansive Machine Music for Machines series and the fugue of Chamber ex Cathedra, a two-minute instrumental named for a narrowing that speeds things up has a positional logic. No lyrics. The title does the analytical work.
