Announcement of microtonal festival

Next month there is another microtonal festival in the Netherlands.
The occasion is the 50 years existence of the Dutch microtonal movement
that was started by Fokker. In august 1946 were the Euler-Fokker genera
presented to the general public by a radio broadcast of Martin Lu"rsen's
Modi Antichi Musiche Nuove. In 1950 Fokker had the 31-tone organ built.
In 1960 he founded the Stichting Nauwluisterendheid. That was a well
chosen name, but contains a double meaning that's hard to translate.
Later the foundation became Stichting Huygens-Fokker.

The events are these:

Sunday 6 October 13.45, lecture about Turkish classical music by Wouter
Swets and 15.00, concert by ensemble Farabi. Teylers Museum, Haarlem.
The musicians are Kamil Abbas, gija"k, violin, rawap and song,

Een grotere verscheidenheid aan microtonen is nauwelijks denkbaar. Van
de Arabische 3/4-tonen in Ton de Leeuws compositie, de effectieve en
vaak zeer virtuoze 31-toonsmuziek van Henk Badings, waarbij spontaan
jazz-achtige accoorden ontstaan, tot de lyrische `ekmelische'
intervallen van Franz Richter Herf. Het voordeel van een
strijkinstrument is dat theoretisch gesproken elk microtonaal interval
gespeeld kan worden. Dat dit in de praktijk een zeer moeilijke opgave
is, blijkt wel uit de enorme studietijd die de musici moeten investeren.
Niet alleen hun vingers moeten zoeken naar nieuwe grepen, ook hun gehoor
moet worden getraind in het onderscheiden van zeer kleine intervallen.
Nu de luisteraar nog.
Herf (1920-1989) was jarenlang verbonden aan het Mozarteum in Salzburg,
waar hij een instituut voor Ekmelische Musik (72-toonsmuziek) oprichtte.
Het Stadler Quartett heeft zich, op verzoek van dit instituut,
gespecialiseerd in microtonale muziek. De spelers hebben inmiddels een
indrukwekkend repertoire opgebouwd, waarvan het grootste deel speciaal
voor hen werd gecomponeerd.
Dit programma maakt deel uit van een festival ter gelegenheid van het
50-jarig bestaan van Stichting Huygens-Fokker, het centrum voor
microtonale muziek. De overige aktiviteiten vinden van 6 t/m 13 oktober
plaats in het Teylers Museum te Haarlem. Voor meer informatie over het
programma van het festival: tel. 020-6921593.

Wees daar of wees vierkant!

On Fri, 13 Sep 1996, it was written:

It's interesting to note that the first ETs to be level 2 consistent at
the 5- and 7- limits (12 and 31) are actually level 3 consistent at
those limits as well. I took a quick pass through the file and found
that the first ET to be level 3 consistent at the 9-limit is 171 (which
is actually level _8_ consistent! holy cow), and at the 11-limit, 342.
I couldn't find any ET under 1200 that was level 3 consistent at the
13-limit.
