@sgf@mastodon.xyz @astrid@fedi.astrid.tech @lily@glaceon.social oh my god what, no, i've never heard of this nonsense? what the hell?
like half of all the one-digit integers are Fibonnaci numbers
0 ✅ sort of
1 ✅✅
2 ✅
3 ✅
4 ❌
5 ✅
6 ❌
7 ❌
8 ✅
9 ❌
it's hardly a surprise that the 5 and the 8 hit, and the 13 is just those added together so that one's free
and that's assuming you count from C. what if you're playing in C#? Then an octave has six black notes and seven white notes, those aren't Fibonacci numbers! there are three non-fibonacci numbers lower than 9 and you've hit two of them.
why do all the maths cranks focus purely on ϕ and cantor's diagonalisation theroem

@andrewt@mathstodon.xyz @sgf@mastodon.xyz @lily@glaceon.social I'm glad enough that biblical numerologists don't know anything beyond addition and multiplication. It would be cursed as hell if they started pulling out angel-topological arguments for the day of judgement

@andrewt@mathstodon.xyz e.g. https://www.goldennumber.net/music/ ! It's one of those things that just gets repeated around by people who don't really get the maths. To be fair, "black and white notes" are more accurately 8 notes in a tonal scale (really 7), selected from 13 notes (really 12) in the octave. "Black and white" is just explaining that in the context of C major.
