The piece starts by giving the violin one law: a repeated descending ground. Structure is not built by contrast yet. It is built by making the return unmistakable.

The same descent keeps returning, but pressure, register, and articulation change the weight of each pass. The form teaches the ear to hear small difference as event.

Around 2:28, the surface becomes more active against the stable ground. Double-stops and implied voices make the solo violin feel briefly crowded without adding another instrument.

At 4:15, the structure tightens into interlock: steady count below, active hand above. The short loosening after 4:38 matters because the law returns with changed force.

The middle-late span keeps finding new surfaces on the same descent. By 6:42, the interlocking grid returns more exacting, turning variation into discipline.

The ending does not escape the ground. It lets the repeated path lose authority by degrees until the final break leaves the form as memory.
