In music, a breedsma is an interval between pitches with the ratio of 2401:2400, which is the difference between the septimal diesis (49:48, also known as Slendro diesis) and the septimal sixth-tone (50:49, also known as jubilisma). It is about 0.72 cents ( Play (help·info)).
- 2401/2400 = 128/75 / (8/7)4
- 2401/2400 = (7/6)4 / 50/27
It is therefore the difference between one kind of classic diminished seventh and four septimal major seconds, or four septimal minor thirds and one kind of classic major seventh.
