:I am a member of Orfeó Valencià, from Valencia (Spain).
:I am conducting a research about just intonation, and I have created the web sites about the subject listed above, whith a section (http://www.justaentonacion.com/obras/intro.htm) about implementation of just intonation in real musical works (annotated scores, sound files, harmonic analysis...).
:I am also the author of the novel [https://www.amazon.es/dp/B00V8T8G12 Un himno a la alegría] (in Spanish) / [https://www.amazon.es/dp/B00V8T995O Un himne a l'alegria] (in Catalan), based in my choral experience, and that deal with the topic of just intonation too.
