There is a law in Mexico protecting the National Anthem. One of its articles states that it must be performed following the Official Score. Every Monday morning, across the country, millions of Mexican children violate it — with complete conviction.

I was one of those children. What I absorbed, before I had any theory of pitch, became the ground of my music — not a compositional decision but a terruño, a native soil. This piece is where I distilled that out, and its the origin of all pitch designs in my music.

What we kids produced is not the anthem and not its absence. It is a turbulence of frequencies with a single direction — not a melody, but the shape one leaves behind. Multiplied across hundreds of voices, that gap becomes the material — a constant. The residue is the music.

This points toward what might be called a Theory of Attuned Cultures — cultures whose pitch practice is constituted by immanent pitch turbulences that have never been theorized and that form a unified, massive, unquestioned identity. Persian classical music also falls outside the Western tempered grid — but systematically, theorized across centuries into an elaborate modal science. As were the musical traditions of ancient Mesopotamia, the Indus Valley, the Chinese and Japanese imperial courts. An attuned culture does neither. It simply never attended to it.

The stage replicates the elementary school flag ceremony. A woman marches on with a large flag. A voice asks the German audience to remain silent and the Mexican audience to stand. The conductor receives the flag and uses it as a metronome — a full-body baton for eight musicians aligned at the back of the stage. In darkness, a spotlight on the flag.

The eight musicians play the military percussions that always accompany the anthem — the official skeleton. The pitches they assign to each attack are entirely their own, Ad Lib: a turbulence of eight, none of them the score. On two large screens, documentary footage of Mexican schoolchildren singing exactly as I remember — attuned to nothing but each other. A solo singer begins as a child, inside the collective memory, and gradually moves into the improvised language of a trained soprano — the technique that grew out of the turbulence without ever fully leaving it. 

Everything builds — not faster, but louder. The ceremony becomes overwhelming at the same tempo, the same illegal pitch. Then she is alone. A short introspective solo, after the crowd.
