'''50/49''', also known as the '''small septimal sixth-tone''', '''small septimal diesis''', '''septimal tritonic diesis''', or '''jubilisma''', is a [[7-limit]] [[medium comma]]. It is the only [[superparticular]] [[comma]] in the 7-limit aside from [[126/125]] and [[4375/4374]] which has a numerator which is neither square nor [[triangular number|triangular]], meaning it is not the difference between septimal superparticular rations with numerators differing by either one or two. Instead, 50/49 = ([[10/7]])/([[7/5]]).

It cannot be tempered out if all of the consonances of the 7-odd-limit are distinct, however, it ''can'' be equated with other commas; for example:
''It cannot be tempered out if all of the consonances of the 7-odd-limit are distinct'', however, it ''can'' be equated with other commas; for example:
* ([[36/35]])/(50/49) = [[126/125]]
* ([[36/35]])/(50/49) = [[126/125]]
* ([[45/44]])/(50/49) = [[441/440]]
* ([[45/44]])/(50/49) = [[441/440]]
