Matteo,
I am NOT a troll, but I am a ferocious amateur in all matters, a
plunger, a tourist , a dilletant, the fool who enters in where wise
men fear to tread, etc. I get a real joy from stumbling on the
relations between things. And then wondering if the relations I have
stumbled upon are merely superficial, or have some profundity to
them. So, while I can take delight in a relation between mathematics
and music, I really know relatively little about either. So when you
produced "If I had a ribbon bow" in the midst of a mathematical
discussion, it was for me a wonderful moment. And then I am tempted
to fold the argument back on itself and ask is there anything
mathematical about major and minor modes, in general, or that tune, in
particular. I did wonder if illumination might be gotten by focussing
on the intervals of the modes on a 12 tone scale. So if we write them
out starting at random, and going a couple cycles for completeness
sake, we capture both the major and the minor modes depending only
upon where we start.
*2,2,1,2,2,/_2,1_/*/_,2,2,1,2,2_/,2,1
I am, in my plungerish sort of way, interested in what this implies
about the semantics of mathematics. I have a long thread with Frank
of this list in which we agree that mathematics, to the extent that it
is a distinct field, has no semantics whatsoever.
As to ChatGPT (George), he, like me, is a plunger. Contrary to
EricS, I did NOT consult him until after I had consulted you-all. I
was surprized when he got the answer first pass. I flagged Jon Z on
my original post, not because he is a mathematician, but because he is
also a musician. As such, I thought he might break the semantic
frame that others became ensnared in.
By, the way, to me, a troll is someone who delights in making others
angry. I actually fear the anger of others.
All of which is probably irrelevant to your last post, to which I
should probably have responded, "I did not understand."
Nick

Likewise, Nick!
I see multiple tangents departing from the original conversation, and
I'm happy to roll back to the original thread.
You're spot on, save for a constant of integration. The completion I
had in mind was supposedly 1, 6, 1, [polyphony ensues, sorry 6,10], 1,
8, 6, [1,10] ( _https://www.youtube.com/watch?v=Va87qt0VZ2M

Great to hear from you Matteo,
I have no idea mathematically what 1,3,4,6,8,11,10; is, but
musically its the first 7 notes of "if I had a ribbon bow"
(_https://www.youtube.com/watch?v=rkXwfsGBupM
<https://www.youtube.com/watch?v=rkXwfsGBupM>_). In that case the
completion would be,
6,8,8, 8, 8, 8;
But what is it really?

Were it so, we'd need the next number {16,17} to
tell the difference. But like many of Nick's
riddles, I have no idea what he intended.

I am assuming you are thinking of a
polynomial that generates each sequence.
Unfortunately, it's a 6th degree polynomial
and so solving for the coefficients is a pain.
You construct a Vandermonde matrix (V) a
vector of dummy coefficients a = [a0, a1, ...,
a6]. Then you solve for the coefficients
relative to your sequence (S), V * a = S.
Python helped nicely:
import numpy as np
n1 = np.array([0, 1, 2, 3, 4, 5, 6])
y1 = np.array([1, 3, 5, 6, 8, 10, 12])
coeffs1 = np.polyfit(n1, y1, 6)
sol1 = np.polyval(coeffs, 7)
n2 = np.array([0, 1, 2, 3, 4, 5, 6])
y2 = np.array([1, 3, 4, 6, 8, 9, 10])
coeffs2 = np.polyfit(n2, y2, 6)
sol2 = np.polyval(coeffs, 7)
=>29

Why, and what are we talking about here?
I predict that only Jon will guess the
answer.
Please dont trouble yourself with this
if you have anything better to do.
