It's sad that it only has one example for tanci, a genre I discovered due to this list, that aside from wikipedia is barely documented on the internet. After some searching I've managed to recover about 6 hours / 58 tracks of tanci in a spotify playlist -- most of it under the 'various artists' tag, one of the reasons why it was difficult to find any artists, I expect. I'm sure spotify has more of it and that it's uncategorized and badly labelled.

You can find it here, if anyone is interested: https://open.spotify.com/user/gallefray/playlist/6CzafKwRUi5...

Talk about false advertising. I couldn't find the button that plays all of the samples at the same time.

Here I was expecting silence, as each sound - including each sound's inverse - was played simultaneously.

The bottom of the page is a little weird. "Byzantine" is not Russian Liturgical Music.

This is Byzantine Chant: https://youtu.be/Bs--5yMg1g0

Also, Georgian Polyphony did not involve strings as a general rule. There were regional exceptions, but early Slavic polyphony was generally a capella.

Here's a good example of Gerogian polyphony: https://v-s.mobi/elia-lrdei-princeton-georgian-choirs-fall-2...

Sorry to nitpick, but I hate to see a fascinating corner of music ignored. Happy Listening!

I’ve been told multiple times that I don’t really have a taste in music, because I listen to a confusing mix of genres. This is perfect for me. So much more to discover.

You're not the only one. I have tastes in music, even strong ones, but they don't tend to follow the way genres seem to be split at all.

Defining a genre by its characteristic instrument set, for instance, doesn't match how I tend to react to things very well, but it's a fairly popular way of separating genres, it seems. (I'm not saying I don't understand the use of that metric, it's very, well, available, in the sense of "availability heuristic". But I do not personally find it all that useful.)

Depends how you take the sum!

[edit] See my comment below: my joke is about the fact that, depending on the order in which you sum an infinite sequence of waveforms, you can create a sequence that converges to any sound you want [1] (as long as those waveforms together span the full frequency space). Note also that a sum over a truly continuous space of arbitrary waveforms is even more ill-defined.

Sound waves are physical. You cannot change the empirical outcome by doing the math differently.

Sound waves are indeed cancelled out by their inverse.

This would make sense if it were physically possible to play every noise at once. (Where would you place the infinitely many emitters? If they have any displacement at all, then there will be points that would not experience destructive interference at all frequencies.)

This site just gave me a nostalgic flashback to the type of thing I'd stumble across (heh) via StumbleUpon.

Isn't the inverse of a sound the same sound?
