About a year ago, I made a setting of the Litany of Tarski for four-part a cappella (i.e. unaccompanied) chorus.
More recently, in the process of experimenting with MuseScore for potential use in explaining musical matters on the internet (it makes online sharing of playback-able scores very easy), the thought occurred to me that perhaps the Tarski piece might be of interest to some LW readers (if no one else!), so I went ahead and re-typeset it in MuseScore for your delectation.
Here it is (properly notated :-)).
Here it is (alternate version designed to avoid freaking out those who aren't quite the fanatical enthusiasts of musical notation that I am).
Because musicians from low-wage countries can compete in such a market.
It would need to be a really low-wage country for a couple of bucks to be enough to make it worth enough singers' time. My impression is that super-low-wage countries tend not to have flourishing communities of musicians experienced in the Western art music tradition, and I'd guess they're also not the easiest places to get hold of the equipment required to make decent recordings.
