Thank you, Matteo, for Jacob Collier. I never would have encountered him without you. I stuck with the video below, for the whole 30 minutes. It had me tearing up and grinning in equal measure the whole way through, of only because I kept expecting to trip over the dangling strap to his orange overalls.

I deserved death by definite article and was, as the gladiator by the Emperor, spared. Also, while I am in, let me farm out a problem. The following tune, played on the black keys starting with C#, has been bedeviling me for years. I remember the words as, I'm a man with no heart to give, {Mandy} Oh [Mandy] I put the name Mandy in brackets because there is a song called Mandy and this is not it. None the less, that is the way I remember it. The tune of "my" song, starting on D# is: 1,3,6,8,10, 13, 15, 18; 3, 10; 8,6, 3, 10. You-all could put me out of a lot of misery if you knew it. I suffered for years from a Christmas carol I remembered from my childhood, which I could find on no website of carols, British or English. It turned out to be written by the music teacher in my 7th grade music class and never published or sung anywhere else, so far as I have been able to find. It's a bit like the Coventry Carol. The words of the first 2 verse2 are... We'll journey to Egypt. We'll go, husband dear, We'll journey to Egypt No lingering here. [Second half of this verse missing] He's killing the children, In village and farm. He's Killing the children Who've never done harm Poor wretches, the mothers, Are helpless in woe, Behold how in weeping, And mourning they go. I can send you the notes if you like it.

Music theory is a good kind of "down-the-rabbit-hole" situation which I had entertained for a long time. Spoiler: we (most of us) have been living in a lie the whole time, equal temperament is a compromise and modern western music intervals sound wrong by necessity/construction. A short clip featuring this British kid - an innate talent unfortunately made to become a Barnumesque human oddity - can be your red pill moment: https://www.youtube.com/watch?v=RGDWXe2u9kw Not being ensnared in any particular semantic frame (I own a black belt in amateurishness), mapping those numbers to pitches (I'm intentionally not using the n-word) came quite naturally. I apologise profusely for my hard to read post, the constant of integration thing was supposed to convey the idea of transposed melody (by 3 semitones if I counted right). In other words, you've found a different pattern (If I had a ribbon bow) which also matches my sequence in a different key. To wrap this up, I'd be delighted to delectate [1] on the 12 tone scale, but I'm hesitant to overfit the conversation onto this very ethnocentric concept.

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."
