Show HN: Modern music is slightly off tune, here is an instrument that isn't
Musical harmony is all about sound frequencies related to each other by simple ratios, like 3&#x2F;2 and 5&#x2F;4. For the past few hundred years Western music has been using a tuning system in which these simple fractions are approximated by powers of the twelfth root of 2. This brings some practical musical advantages, but even the average listener can hear the difference, the loss of purity of harmony. I made an instrument that instead uses a tuning system called just intonation, that uses pure, exact fractions only.<p>The link opens with the help overlay of the instrument. It reads like a blog text explaining tuning systems and just intonation. If you would rather poke at things than read, then click the X on top left to close the overlay and just play with the thing.<p>Source code is at github.com&#x2F;mhauru&#x2F;Jintone.
