Just Intonation vs Equal Temperament
Why Hacker News recommends it
Shared as a quick audible demonstration of the errors that equal temperament introduces compared with pure intervals.
What it is
A short demonstration comparing just intonation with equal temperament, played so you can hear how the tuning compromise changes intervals and chords. It includes a Bach prelude played in both tunings.

This looks neat. I wish I could try it on my iPad. There is a lot of interesting mathematics behind music. I particularly enjoy reading about different temperaments, which are our attempts to compromise between just intonation (the harmonic-based scales the article mentions, which ostensibly sound the most "natural" and "correct" in a given key), and physical instruments, which we usually want to be able to play in multiple keys without significant adjustment. Twelve-tone equal temperament is the most common temperament in Western music, where the frequency of each semitone is the frequency of the previous semitone multiplied by the twelfth root of two. With equal temperament instruments, th

With equal temperament you actually don't modulate precisely, so there is always weird disharmonic sound every single time. As I said, for some electronic music subgenres it's a welcome feature; it would shock classical composers if they ever heard such a version though. Have you ever thought why do you need to state scale at the beginning of a classical piece if you can just easily transpose song to whatever scale you like? Well, those scales sounded differently and each composer was exploring what sounds best in a given scale. Watch this: [this video] Ever played on a top end concert grand and thinking it sounds weird? Then tried a different tuning and being shocked how much better it sounded?
