Intervals and triads: added mode 3 to table
Line 1,030: Line 1,030:
Mode 3 has 4:5:6 major triads available above E♭, E, F, G♭, and G.
Mode 3 has 4:5:6 major triads available above E♭, E, F, G♭, and G.


The following tables show the (3, 4) and (4, 3) triads available of mode 3 and mode -3 of the Pinetone chromatic scale:

<nowiki>*</nowiki> Non-bracketed JI ratios are those approximated in 2.3.5.11.13 Ptolemismic Pinetone; bracketed JI ratios are the 2.3.7 interval approximated by additionally tempering out 105/104 or 245/243 as in Supermagic temperament.  
<nowiki>*</nowiki> For tables 3.1. non-bracketed JI ratios are those approximated in 2.3.5.11.13 Ptolemismic Pinetone; bracketed JI ratios are the 2.3.7 interval approximated by additionally tempering out 105/104 or 245/243 as in Supermagic temperament.  


Note the major minor third approximating 11/9 and the minor major third approximating 27/22 are very similar in size in this tuning (351.784 and 352.317 respectively). If we equate these intervals, we additionally temper out 243/242, leading to an extension of Tetracot (Wollemia or Monkey if we also equate 13/10 with 9/7 or 21/16 respectively).
