51/50, the large septendecimal sixth tone, is a 17-limit superparticular interval of about 34.3 cents. It is the interval between 17/10 and 5/3, between 17/15 and 10/9, and their respective octave complements.

This interval is the 17th-partial chroma (17-limit formal comma) used to express 17-limit intervals in Ben Johnston's notation, being expressed with a "17", while its reciprocal is denoted as "17" (a turned "17"). If the base note is C, then 17/16 is represented by C–C#17.

Temperaments

When treated as a comma, this may be called the vengeance comma on account of 25/17 being named the veangence subfifth by Eliora in 2021 from a culturally famous Bible passage, Ezekiel 25:17.
