I meant the open tuned strings, they are fix and not tuned with fifths from historic keyboard temperaments, but usually tuned with pure fifths. So i should have better said: every string quartet tune quasi ET on the open strings (slightly narrow fifths, probably quasi P12) to avoid the pythagorean third of the cello c and the violin e, wich will otherwise result when using pure fifths. By doing so, the very sharp pytahgorean third between the cello c and the violin e is transformed into a milder quasi P12 tempered third. The string quartet has two violins (gdae), one viola(cgda) and a cello(cgda) The cello and the violin have the same tuning, but with the cello a twelfth fifth lower than the violin. The cello and the viola have the same tuning, but with the cello an octave lower than the viola. regards, Bernhard Stopper -----Original Message----- Date: Sun, 01 Jul 2007 02:09:48 +0200 Subject: Re: The Acme A1 Temperament From: A440A at aol.com To: pianotech at ptg.org Bernard writes: << every string quartet plays quasi ET (slightly narrow fifths, probably quasi P12) to avoid the pythagorean third of the cello C and the violin >> I disagree. I have sat in many a performance, and rehearsal, with my SAT in my lap. Intonation in a good string quartet is anything but ET, and in fact, I have had a number of string players mention how everything changes when they have to play with a piano. There are no pure thirds in an ET piano, but you will hear a lot of them in a good quartet. Horn players know that they must play the E differently, depending on what key they are in. This doesn't indicate ET is in use in the orchestra...
