The opening pulse is already rigid: low strikes make a floor, and the brass sets its line down in squared blocks.

Higher strings start to answer the brass instead of just riding underneath it, so the block sound gains a sharper edge.

The texture narrows here: the front brass eases back, leaving darker low voices and a tighter tread.

The low repeated pulse returns under the calls, turning the suspended pressure back into forward motion.

The brass line returns broader and more forward, while the strings above it flicker rather than weigh the beat down.

The center thins into quick string motion and clipped brass; the pulse stays exact, but the surface gets tighter.

A familiar block rhythm reasserts itself, and the low brass and percussion give the beat a heavier square again.

Near the finish, the phrases shorten and press forward; the orchestra keeps the grid while packing more weight into each ending.

The final chord hangs, then thins into bare room silence.
