Yeah, I think a good discussion on music theory is starting from first principles, explaining Pythagorean tuning, then explaining 5-limit just intonation, the explaining we compromised on 12-tone equal temperament because it made tuning and

Yeah, that guy tried to argue that Grade 5 ABRSM [1] is “very basic”. Like, excuse me no. “Very basic” is knowing the notes in a major key, and knowing the I IV V chord progression, as well as a basic 4/4 rhythm (8th note hi hats, qu

We recently had a long discussion about this. I come from the “music theory makes a lot more sense once one understands that 2:1, 3:2, 4:3 sound really whole and good to the human ear, 5:4 has a little more tension, and 6:5 has even more t

Click on the switch to the left of the evaluation to run a local Stockfish 19 eval of the position. Showing Black winning in that position is clearly a bug; at 20 ply Stockfish 19 sees a +0.3 edge for White (which is also wrong; it’s about

Alpha Zero Chess never made their code or models public. Leela is based on the same ideas as Alpha Zero Chess, but its model and code are public and uses crowd sourcing to generate and refine the model. Stockfish uses a combination of clas

Interesting bug or regression. Let’s take the very famous game Kasparov - Topalov, Wijk aan Zee 1999 and look at the position just after Topalov accepts Kasparov’s Rook Sacrifice: https://samboy.github.io/blog/Kasparov.

Linux kernel crypto code has resulted in security issues, e.g. CVE-2026-31431. The advantage of using a cryptographically secure stream cipher [1] is that we only need about 128-256 bits of good entropy to generate an arbitrary large number

“Rolling your own crypto libraries is always a bad idea” Absolutes like this aren’t absolutely true. It’s interesting because in a related comment, someone claimed that I was “rolling my own crypto” https://news.ycombinator.com&#

It’s actually an open question of whether “natural” tuning is 3-limit or 5-limit tuning. Five limit tuning, which I discuss above and use to form a major scale, goes back to Ptolemy: https://en.wikipedia.org/wiki/Ptole

Indeed. Bobby McFerrin has a demonstration where, regardless of culture, the pentatonic scale is universal. For the record, a just major pentatonic scale is the notes with the intervals (from the root note) 1, 9/8, 5/4, 3/2

If we teach theory without first principles, all we have to do is say “C + E + G make up a major triad”; we may go as far as to explain that, in a major key, the I, IV, and V chords are major chords, the ii, iii, and vi chords are minor cho

by strenholme 10d ago
Until we have an established scale, unless one has perfect pitch, one note is the same as another arbitrary note. It’s the ratios between notes that make up music.

by strenholme 10d ago
I’m convinced that “Safe and Sound” by Capital Cities became a major hit because it uses an actual trumpet for the lead, causing the perfect intervals to be exact instead of the every so slightly off intervals 12-tone equal temperament has.

It was a really good article up and until it explained the octave, the perfect fifth, and the equal tempered scale. It didn’t do a full explanation of equal temperament—we use it because, with it, it’s easy to change keys. Once it jumps fr

I don’t think it’s unreasonable to say 2/1, 3/2, 4/3, 5/4, and 6/5 are intervals which sound pleasant to the human ear. [1] Once that is established, as per the linked article, 12-tone equal temperament makes a lot

Yes, he could have approached it differently. It’s really good at explaining the octave, the fifth, it shows the mathematical basis for why just intonation has “wolf notes”, and why we use 12-tone equal temperament. Once it hits the 12-tone
