Original Wikitext content:
An //undecimal marvel chord// is an [[Dyadic chord#Essentially tempered dyadic chord]] in undecimal (11-limit) marvel, with intervals in the tonality diamond of the 11 odd limit. Since 225/224 is tempered out in undecimal marvel, 9-limit [[marvel chords]] are undecimal marvel chords. Since 385/384 is tempered out, [[keenanismic chords]] are also undecimal marvel chords. Finally, since 540/539 is tempered out, [[swetismic chords]] are undecimal marvel chords. There are also undecimal marvel chords which are none of these, the essentially undecimal marvel chords. These are four pairs of inversely related tetrads, 1-5/4-11/8-8/5 with steps 5/4-11/10-7/6-5/4 and 1-5/4-16/11-8/5 with steps 5/4-7/6-11/10-5/4; 1-9/8-8/5-7/4 with steps 9/8-10/7-12/11-8/7 and 1-9/8-9/7-7/5 with steps 9/8-8/7-12/11-10/7; 1-9/8-11/8-8/5 with steps 9/8-11/9-7/6-5/4 and 1-5/4-16/11-16/9 with steps 5/4-7/6-11/9-9/8; and 1-5/4-8/5-7/4 with steps 5/4-9/7-12/11-8/7 and 1-5/4-10/7-14/9 with steps 5/4-8/7-12/11-9/7.
