Being an abstract mos degree, and not a specific interval, the diatonic major third does not have a fixed tuning, but instead has a range of ways it can be tuned, based on the tuning of the generator used in making the scale.

The tuning range of the diatonic major second ranges from 342.8 to 480{{c}}. The generator for a given tuning in cents, ''n'', for the diatonic major second can be found by {{sfrac|''n'' + 1200|2}}. For example, the third 192{{c}} gives us {{nowrap|{{sfrac|192 + 1200|2}} {{=}} {{sfrac|1392|2}} {{=}} 696{{c}}}}, corresponding to 50edo.
