A few of Pythagoras' Recent Findings, as Explained to the Layman

1) The Equal Distance Fretted Lute
Since Pythagoras didn't feel comfortable about the equidistant scale steps of the well tempered piano, he would rather approximate the frequencies on a subharmonic scale. This idea turned out to be well suited to the fact that the oud-like instrument that was going to be used could have its frets placed at equal distances, which facilitates its building. In terms of a comb filter: the delay times could be approximated by milliseconds with two decimals of precision, which gives a fairly good approximation at low frequencies, but becomes more and more out of tune with increasing frequency. However, according to Pythagoras, it's in tune all the way.
2) The Groove of a Silver Spoon
Pythagoras decided to believe, that there had to be an Einhet der musikalischer Zeit somewhere, and if there were, at that time, no actual physical phenomena corresponding to such an idea, at least it should be possible to construct one in the laboratory. What about generating rhythms from a spectral analysis of the sound of a silver spoon? Try this: first lower the pitch and speed about 10 octaves, then choose every positive (or negative) peek in the wave form generated through additive synthesis of various components of the spectrum. These peeks are then used to position rhythmic events. Any spoon playing virtuoso knows there are simpler ways to achieve this.
3) Melodic Convolution
Surely Pythagoras knew about Cartesian products and tensor products even before they were invented by others, but maybe this technique is more accurately described as the convolution of two musical objects. But most of all it resembled a special case of the canon: Each note in one of the musical objects was taken as the point of departure for the whole second object, both in pitch and time.

4) A Silver Scale
As Pythagoras noted very early in his career, it is often the case that the scale systems in use in a particular musical community show a strong correlation to the spectra of favored instruments. This hypothesis is well known to musicologists, but why not use it constructively? So, for a musical phrase played on the piano, to be transposed to an inharmonic bell sound,  the scale would be changed accordingly. A new scale is easily generated from the set of transposition ratios between successive partials.
