85/64, the septendecimal fourth, is a 17-limit interval that closely approximates 4/3, from which it differs by 256/255. Because it differs from 15/8 by 24/17, this interval is an easy substitute for 4/3 in scales where one desires to simultaneously maintain Rothenberg propriety and ensure that all notes in the scale suggest the Tonic as the virtual fundamental when played simultaneously.
