Exoplanet Puzzle Cracked by Jazz Musicians
- grzm 9y agoWhile there is a puzzle as to why the orbits of the planets have the relationship they do and how stable it appears to be, in no way is it accurate to that the musicians have somehow "cracked" or explained it. They've taken the pattern and arranged music based on it. That is cool in and of itself, but this title reaches much too far.
- camtarn 9y agoDoes the chord sound kinda ... off to anyone else? I'm wondering whether this is because the note ratios aren't quite right to fall into a western twelve-tone scale, or whether it's just me! Also - the headline isn't really very accurate. The puzzle (how the planets' resonance intervals could have remained stable over a long period of time) isn't actually fully understood; it's just that a paper has explained how it could stay stable for longer than previously thought. And the jazz musicians weren't even involved in that paper - they're only really involved in communicating why the problem is interesting.
- uryga 9y agoyeah, one of the lower notes is way out of tune
- Ericson2314 9y agoYeah chord sounds like shit. Just tuned, as it is called with perfect intervals, it should sound wonderful, and anything else wouldn't really be stable in the way the astronomy portion of the article seems to say.
- Ericson2314 9y agoFor the record, equal temperament is needed to make certain complex chord progressions sound good, but individual static chords always should sound best with just intonation.
- yellowapple 9y agoWith certain instruments (voice, strings, and trombones, namely; valve/rotor brass instruments with finger-actuated tuning slides can pull this off, too, depending on the arrangement), just intonation should work for nearly all chord progressions, since the instrument is not constrained to particular pitches and thus can freely move around to adjust for each chord in quick succession.
- Ericson2314 9y agoRight I wouldn't call that just intonation though, since pitches do not have a static fundamental frequency. I'd love to write a program that, given some midi, finds the perfect such dynamic tuning. Then something else can either synthesize with that directly, or fake it with the pitch weel.
- Ericson2314 9y agoDrums sound interesting to me because of the phase offsets—the polyrythms alone aren't so exotic. I wonder if those match the planets'.
