  • Page 48: Temperaments Of The Chorum Organs

    Chorum User Manual Viscount 10.3 TEMPERAMENTS OF THE CHORUM ORGANS In addition to equal temperament, with the Chorum organs you can play other temperaments described below.

  • Page 49 Viscount Chorum User Manual MEANTONE 3# - MEANTONE 3b This tuning is the prototype of all temperaments based on fifths reduced by ¼ of syntonic comma. This generates eight pure major thirds: Eb, Bb, F, C, G, D, A, E. However, the other thirds are unsuable (B, F#, G#).
  • Page 50 Chorum User Manual Viscount CHAUMONT A meantone temperament; the wolf fifth has been improved by enlarging the fifths on Eb and Bb. There are six pure major thirds: F, C, G, D, A, E. The third major on B, although not very pleasant, can still be used.
