| Interval information |
dhanvantarisma
Thothoru comma
reduced
169/168, the buzurgisma or the dhanvantarisma is a superparticular ratio measuring about 10.3 cents. It is the difference between the neutral seconds of 13/12 and 14/13 as well as between the neutral sixths of 21/13 and 13/8.
Temperaments
Tempering out this comma in the 13-limit gives the rank-5 buzurgismic or dhanvantarismic temperament. Tempering it out in the 2.3.7.13 subgroup gives the rank-3 buzurgic or dhanvantaric temperament. In such systems, 13/12 and 14/13 are equated, enabling buzurgismic or dhanvantarismic chords. This is very comparable to tempering out of 121/120, which results in biyatismic, in which 11/10 is equated with 12/11.
Besides tempering, the interval serves as a period in the 13-limit temperament oganesson, where it is equated with 1/118th of the octave.
Etymology
The buzurgisma was named by Margo Schulter in 2012. The name comes from the buzurg aka buzurk genus by Safi al-Din Urmavi, which features a neutral second[1][2].
The dhanvantarisma was presumably named by an unknown guest in 2011 since it seems this wiki was the place where it made its first appearance[3].
