'''Marvel''' is a [[rank-3 temperament]] with the same [[lattice]] structure as [[5-limit]] [[JI]], while identifying the [[7/4\|harmonic seventh (7/4)]] as a stack of two [[15/8\|classical major sevenths (15/8)]] [[octave reduction\|octave-reduced]], [[tempering out]] [[225/224]].

	Marvel tends to tune [[5/4]] flat, such that a stack of two such thirds give a sharp [[14/9]], and a stack of three such thirds give a sub-octave of [[35/18]] just short of the octave by a quartertone of [[36/35]]. The canonical [[11-limit]] [[extension]], sometimes aliased ''unimarv'', identifies the quartertone as [[33/32]], so that [[11/8]] is that plus a [[4/3\|perfect fourth]]. This adds [[385/384]] and [[540/539]] to the comma list and makes it a member of both [[keenanismic temperaments\|keenansimic]] and [[swetismic temperaments]].

	In the 7-limit, the optimal way such as that taken by [[TE]] and derivatives to close out the comma 225/224 is to tune primes 3 and 5 flat, and 2 and 7 sharp. If we tune the octave pure, the other inclinations remain. This indicates that the diminished third [[~]][[256/225]] should be sharp (towards [[~]][[8/7]]), the augmented second [[~]][[75/64]] be flat (towards [[~]][[7/6]]), the diminished fourth [[~]][[32/25]] be sharp (towards [[~]][[9/7]]) and the tritone [[~]][[45/32]] be flat (towards [[~]][[7/5]]), such that every [[7-limit]] [[9-odd-limit]] interval is tuned between itself and the [[5-limit]] interpretation it is separated from by [[225/224]]. If we take these as hard constraints, then [[53edo]] and [[84edo]] are the smallest edo tunings to satisfy them, but if overtempering is allowed, many smaller edos are possible, such as [[31edo\|31-]] and [[41edo]]. Interestingly, [[72edo]], though very performant as a 7- and 11-limit tuning, is overtempered for some of these constraints, whereas 53edo, though satisfying these constraints, tempers the intervals closer to the more complex [[5-limit]] interpretations, though the 7-limit concordances of the 9-odd-limit still clearly work. [[84edo]], another superset of 12edo, is an interesting edo to look at for its high performance in large odd-limits. Going up to larger edos, [[125edo\|125-]], [[166edo\|166-]], [[178edo\|178-]], [[197edo\|197-]], and [[240edo]] are all great choices with different intonational characteristics.

	The marvel extension [[hecate]] has the no-17's [[19-limit]] as its subgroup, and ~~tridecimal marvel, the extension chosen by [[Gene Ward Smith]],~~ is in the 13-limit.

'''Marvel''' is a [[rank-3 temperament\|rank-3]] [[regular temperament\|temperament]] with the same [[lattice]] structure as [[5-limit]] [[JI]], while identifying the [[7/4\|harmonic seventh (7/4)]] as a stack of two [[15/8\|classical major sevenths (15/8)]] [[octave reduction\|octave-reduced]], [[tempering out]] [[225/224]]. It is the head of the [[marvel family]].

	The canonical [[11-limit]] [[extension]], sometimes aliased ''unimarv'', ~~which~~ adds [[385/384]] and [[540/539]] to the comma list makes it a member of both [[keenanismic temperaments\|keenansimic]] and [[swetismic temperaments]].		Marvel tends to tune [[5/4]] flat, such that a stack of two such thirds give a sharp [[14/9]], and a stack of three such thirds give a sub-octave of [[35/18]] just short of the octave by a quartertone of [[36/35]]. The canonical [[11-limit]] [[extension]], sometimes aliased ''unimarv'', identifies the quartertone as [[33/32]], so that [[11/8]] is that plus a [[4/3\|perfect fourth]]. This adds [[385/384]] and [[540/539]] to the comma list and makes it a member of both [[keenanismic temperaments\|keenansimic]] and [[swetismic temperaments]].
