'''56/45''', the '''septimal narrow major third''', or '''~~marvelous~~ major third''', is the interval between various [[9-odd-limit]] consonances – 5/4 and 14/9, 9/7 and 8/5, 9/8 and 7/5, and 10/7 and 16/9- with it also being [[6/5]] away from the marvelous fifth, [[112/75]]. [[Marvel]] tempering makes all of these intervals into major thirds ~~like any other~~, and turns chords like ~~1-5~~/~~4-8~~/5 or ~~1-5~~/~~4-14~~/9 into [[~~Dyadic_chord|~~essentially tempered dyadic ~~chords~~]]. It is a third of a cent flatter than the 6\19 major third of [[19edo]], however, it functionally doubles as a type of diminished fourth. According to [[Ozan Yarman]], the perde segah of [[Arabic, Turkish, Persian|Turkish maqam music]] should range from 56/45 to 5/4.

'''56/45''', the '''septimal narrow major third''', or '''marvel-ptolemaic major third''', is the interval between various [[9-odd-limit]] consonances – [[5/4]] and [[14/9]], [[9/7]] and [[8/5]], [[9/8]] and [[7/5]], and [[10/7]] and [[16/9]] – with it also being [[6/5]] away from the marvelous fifth, [[112/75]]. It is flat of the [[81/64|Pythagorean major third]] by [[3645/3584]], namely a [[81/80|syntonic comma]] plus a [[225/224|marvel comma]]. [[Marvel]] tempering makes all of these intervals into classical major thirds, and turns chords like 1–5/4–8/5 or 1–5/4–14/9 into [[essentially tempered dyadic chord]]s. It is a third of a cent flatter than the 6\19 major third of [[19edo]]; however, it functionally doubles as a type of diminished fourth, flat of the [[8192/6561|Pythagorean diminished fourth]] by [[5120/5103]]. This gives rise to the name '''hemifamity diminished fourth'''.

According to [[Ozan Yarman]], the perde segah of [[Arabic, Turkish, Persian music|Turkish maqam music]] should range from 56/45 to 5/4.
