What vibrating matter produces without instruction. The genuine warrant, and the thing every borrowed authority over sound points back at.
🜃
When any physical body vibrates, a string or a column of air or a membrane or a bell or a vocal cord, it does not vibrate at one frequency. It vibrates at many at once. The lowest is the fundamental, and it is what the ear identifies as the pitch.
The ratios are exact. Given a fundamental at f, the body also produces 2f, 3f, 4f, 5f, 6f, 7f and onwards: integer multiples, ascending without theoretical limit, diminishing in amplitude as they climb. The same series for any vibrating body of any material in any century.
And the intervals those ratios make are specific. 2f against f is the octave, which the ear takes as the same pitch higher up, and which nearly every musical culture has recognized as a unity. 3f against 2f is the perfect fifth. 5f against 4f is the major third.
This is the body that every vestment over sound borrows, and the borrowing is the tell: nothing appeals to the overtone series except a configuration that needs a warrant it did not generate. The series is real, physics-derived, cross-cultural, and prior to every tuning built on it or claiming descent from it.

WHAT THE EAR DOES WITH IT
The ear does not hear the series as separate pitches. It fuses them into one perceived tone: the fundamental, colored by the particular amplitudes of its overtones. That fusion is timbre, and it is why a violin and a flute sounding the same pitch are not the same sound.
A creature who hears a single tone is already hearing a harmonic field compressed into one identified pitch, which means the measurement cut is operating below the level any musical training reaches.
So the training of an ear in any tuning is training in how to handle what perception has already partially handled. The tempered practice takes an ear that is compressing at the level of tone and teaches it to compress again at the level of interval.

COMBINATION TONES
Two tones sounding together do not simply coexist. They interfere, and the interference produces frequencies present in neither and generated by no instrument.
The primary ones are the sum tone, f1 plus f2, and the difference tone, f1 minus f2. Two voices at 200 and 300 Hz, which is a just fifth, produce a difference tone at 100 Hz: an octave below the lower voice, audible in the room, sung by nobody.
In just intonation, where intervals are tuned to the exact ratios, the difference tones land on frequencies that are themselves in the overtone series of the fundamental. They reinforce. The room has something to resonate with.
In equal temperament, where every interval but the octave is slightly wrong against the series, the difference tones land slightly off it. The mistuning is small enough that the ear forgives the intervals and large enough that the combination tones no longer reinforce, so what is lost is not heard as wrongness but as absence.
This is what Beissel produced at Ephrata by training singers from the series rather than from a keyboard. The difference tones landed where they could reinforce. The emergent frequencies visitors kept describing, sound arriving from the walls and from between the bodies, were that.

THE SEVENTH HARMONIC
The series runs without theoretical limit, and it parts from Western practice at one specific and revealing place.
7f against the fundamental gives an interval near a minor seventh and flatter than any minor seventh in equal temperament or in standard just intonation. It is neither the minor seventh the tempered grid recognizes nor any ratio the received just intervals supply. It falls outside the categories, which is a different thing from falling outside the physics, and the categories are what get called nature.
It is not absent from practice, only from the parts of practice the grid administers. Barbershop singing tunes the dominant seventh chord towards 4:5:6:7 and gets its characteristic ring from doing so. And the blues keeps it present as the blue note, the flattened seventh whose refusal to settle into the authorized positions is the tradition's whole character.
So the series behaves at this edge the way it behaves at every edge of every format: producing what the format was built not to receive, and going on producing it regardless of what has been decided about what physics is permitted to make.

THE WARRANT AND THE DERIVATION
The overtone series is the genuine warrant that the vestment over harmony borrows, and the diagnosis does not require denying that the warrant is genuine. The series is real. The intervals are natural. The relationships are written into vibrating matter and not into anyone's decision about it.
What is done with the warrant is specific. Select from the series the intervals that can be administered through twelve keys. Adjust those intervals so that any key is as available as any other. Install the adjusted set as the complete natural harmony. Then cite the series as the authority for what has departed from it.
The warrant is genuine and the derivation is false, and holding both at once is the whole of the reading: the tempered practice descends from a decision about mobility, retroactively legitimated by selective appeal to physics it has in fact left behind.

🜃
Taking the warrant back is not a counterclaim to be its authorized interpreter. It is following the series where the vestment declines to go: just intervals, the seventh harmonic, the difference tones that arise from actual acoustic encounter rather than from the ones a grid can name.
And the series is not this tradition's property either. It belongs to vibrating matter, which produces it without instruction and without permission, and which was doing so before anyone arrived to license it.
What is refused is only the claim to stand between a creature and what any string will tell her.
