These charts offer another way to explore what you hear. Times begin at the start of this excerpt. Open a chart for a closer look, or save the report and candidate chord timeline for use at the keyboard.
The harmonic layers
The waveform, pitch-class maps and estimated bass show how the layers change through the excerpt.

Sound across the registers
Brighter bands show stronger frequencies. Organ overtones and reverberation also appear here; a bright band is not necessarily a separate played note.
Open full-size chart ↗The candidate chord timeline
A compact CSV for a spreadsheet: excerpt times, pedal/bass, upper pitches, competing chord readings and tonal context. These estimates are not an engraved transcription.
Download chord timeline ↓Listen for the layers
Hear the bass move C → A → A → Bb → C. Listen especially from 5 to 15 seconds: the A bass continues as the upper harmony changes from F major to D minor.
The known source harmony
Five equal sections were constructed as C7 → F/A → Dm/A → Gm/Bb → C7. The source is deliberately simple. The displayed timeline contains actual machine estimates, not this source progression copied into chord labels.
Context remains a musical question
The phrase can suggest a C dominant field preparing F, but this exercise does not end with a resolving F chord. Listen to the whole shape rather than declaring a modulation from an isolated upper chord.
