//Marvel chords// are [[Dyadic chord#Essentially tempered dyadic chords|essentially tempered dyadic chords]] tempered by the marvel comma, 225/224. The **marvel triad**, aka **marvel augmented triad**, or **septimal augmented triad**, is a marvel chord which in close position consists of two major thirds of approximately [[5_4|5/4]] and a supermajor third of approximately [[9_7|9/7]], or in other words a 5/4-5/4-9/7 chord, which closes at the octave since the [[marvel comma]], [[225_224|225/224]], is tempered out. In [[meantone]] this [[triad]] consists of two major thirds and a diminished fourth, the classic augmented triad of the meantone era. It can also be described as a marvel-tempered version of a 1-5/4-[[14_9|14/9]] chord. Another marvel essentially tempered triad is the 5/4-9/8-10/7 chord and its inversion, which means the marvel tempering of 1-5/4-7/5 and 1-10/7-8/5. There are also marvel tetrads: the 5/4-9/8-10/9-9/7 chord and its inversion, temperings of 1-5/4-7/5-14/9 and 1-5/4-8/5-16/9; the 5/4-9/8-8/7-5/4 chord and its inversion, temperings of 1-9/8-7/5-7/4 and 1-5/4-7/5-8/5; the 5/4-9/8-5/4-8/7 chord, the tempering of 1-5/4-7/5-7/4; and the 9/8-10/9-9/8-10/7 chord, the tempering of 1-9/8-5/4-7/5. There are also two marvel quintads, the 9/8-10/9-9/8-5/4-8/7 and its inverse, which are the temperings of 1-9/8-5/4-7/5-7/4 and 1-9/8-5/4-7/5-8/5. Equal temperaments with marvel chords include [[19edo]], [[22edo]], [[31edo]], [[41edo]], [[43edo]], [[50edo]], [[53edo]], [[72edo]], [[84edo]], [[94edo]], [[103edo]], [[166edo]] and [[197edo]].
