Four filter channels from seventy to five hundred hertz
Rejecting the second harmonic and isolating the first
The intonation curve is traced on the screen as the speaker speaks
from a tape of a conversation on a busy Parisian street

Vous nous avez tous vus dans la rue?

A perfect reflection of the fundamental frequency
To the elements of melodic perception, reacting accurately

Phonemes explode from parted lips, aperiodic
Vibrating chords, the rise and fall of speech, melodic
Overlapping vocal overtones above the din
The fundamental underneath when we speak and when we sing

Vous nous avez tous vus dans la rue?

A perfect reflection of the fundamental frequency
To the elements of melodic perception, reacting accurately
