Lyrics:
Verse 1
We stitched 2,680 genomes through long nights, slow and bright,
69.5 million variants spread like a folded light,
Small patterns pulsed until the hidden lines came clear,
A steady hum of markers drawing what was near.

Pre-Chorus
Linkage patterns sharpened — how variants travel together,
PCA and heatmap traces folding into tether,
Imputation filled the gaps; missing calls took flight,
A clearer lattice rising out of quiet night.

Chorus
We traced the missing threads and pulled the map to show,
Where whispers turned to signal, where the small truths grow,
Lift the blurred and turn it certain, make the pathways clear,
From scattered code to meaning, the picture draws near.

Verse 2
Thirty-eight percent stronger against broader panels' spread,
Tens of percent more variants now counted and read,
Polygenic lines nudged forward — modest, true, and bright,
A tool to read the shadows, a better guiding light.

Bridge
Still there are thin borders, rare whispers out of sight,
Singletons and hidden groups remain in the night,
But every clearer block we build narrows what's unknown,
Layer on layer, the map keeps finding home.

Final Chorus
We traced the missing threads and brought the map to light,
Signals rise from silence, patterns hold the night,
Lift the blurred and turn it certain, let the pathways steer,
From scattered code to meaning, the picture stands clear.
