An ixi-style read of the jam window, 4:45 to 9:15, tracked player by player. Where the Hollywood Bowl Chalk Dust was a bright G-major rocker, this Seattle one goes the other way, into a cool F# minor that turns Dorian, a raised sixth keeping the dark key from ever sounding plainly sad. Trey leads, Page climbs in, Mike roams the low end. Every claim traces to a per-stem chroma and spectral-flux pass over all six demucs lanes. The staves are transcribed off the guitar and bass stems with librosa pyin, Trey above Mike. The D# raised sixth that turns the minor to Dorian, and Mike's move to B on the ride-out, are read straight from the audio.
Chalk Dust Torture (jam peak, 4:45 to 9:15) — Phish · 2025-04-19 Climate Pledge Arena, Seattle
F# minor · the entry (4:45 to 5:53) · Trey states the minor triad over a flat-7 bass
Trey leads into a cool F# minor, his guitar working F#, A, C#, the minor triad, the busiest voice from the start. Mike sits not on the root but on E, the flat seventh, giving the floor a modal, unresolved cast rather than a planted minor. Page hangs back on piano, his organ adding F#, C#, G# under Trey. Fishman drives a firm groove. This is the dark mirror of the bright Hollywood Chalk Dust, the same tune steered into the shadows, the b7 in the bass refusing a clean minor cadence.
favorite momentMike opening on the flat-7 E rather than the F# root, the minor floor left modal and unresolved under Trey's triad from the first bar.
F# Dorian · the raised 6th (5:53 to 7:00) · a D# brightens the minor, Page steps in
Mike drops to the F# root and the mode reveals itself. A D# enters the field, the raised sixth, turning the key into F# Dorian, the brighter, jazzier minor that never quite settles into sadness. Trey works F#, E, D#, B, leaning into that major sixth. Page steps up, his piano now an active voice, A, B, G# coloring the Dorian. The dark key opens a window of light, the D# the single note that defines the whole mood.
Dorian deepens · the build (7:00 to 8:08) · the 4th and 6th ring, Page near co-lead, drums peak
The Dorian color deepens. Trey works F#, B, A, D#, the fourth and the raised sixth both ringing over the minor, the modal brightness at its fullest. Page climbs to near co-lead, his piano stating F#, E, B, D#. Mike holds F#, and Fishman drives the drums to their densest of the window. The jam builds without leaving F# Dorian, the energy rising while the mode holds, the light-in-the-dark color carrying the climb.
to the 4th · the ride-out (8:08 to 9:15) · Mike moves to B, Trey peaks
Mike moves the bass to B, the fourth, tilting the jam toward the subdominant for the close. Trey peaks here, his busiest playing of the window, driving F#, D#, E, C# over the move. Page stays strong on A, F#, B. Fishman rides the groove out. The jam ends in motion, the bass having shifted off the root to the fourth, the F# Dorian brightness holding to the end, a dark-keyed Chalk Dust that never let itself turn fully sad.
favorite momentThe raised-6th D# glowing over the F# minor all the way through, the one note that keeps this dark Chalk Dust modal and mysterious instead of sad.
Chalk Dust 2025-04-19's stems carry all six lanes. Page is read across the piano and synth/organ ("other") stems. Fishman's build is from the drums-stem energy, densest in section three. Lead attribution comes from a per-stem spectral-flux pass, Trey the busiest voice every section. Key F# minor at 0.673 correlation, modest because the raised-sixth Dorian color pulls against a plain minor reading, which is the point. Window vocal-gated to the instrumental stretch at 4:45.
