14.2 TEMPERAMENTS OF THE PHYSIS ORGANS
KIRNBERGER II
Based on two fifths, reduced by half syntonic comma, and one fifth reduced by a skisma. There are three
pure majors: C, G, D. Therefore, the major triads on C and G are pure. Same goes with the minor triads, on
E and B. The four major thirds on C#, G#, Eb, Bb are Pythagorean. The coexistence of pure and tempered
chords gives a peculiar character to this tuning.

WERCKMEISTER III
Based on four fifths, each reduced by ¼ Pythagorean comma – the others are pure. Creates three Pythagorean
major thirds on: C#, F#, G#. As the number of alteration in the piece performed increases, so does the
harmonic tension.
