+'''31/30''' is the '''large tricesimoprimal quartertone''' measuring about 57{{cent}}. It differs from [[33/32]], the undecimal quartertone, by [[496/495]] (approx. 3.49{{cent}}). It differs from [[32/31]], another tricesimoprimal quartertone, by [[961/960]] (approx. 1.80{{cent}}); they together make [[16/15]].

+This interval is the 31st-partial chroma (31-limit formal comma) in [[Ben Johnston's notation]], denoted simply with the number "31", while its reciprocal is denoted as <span style="display: inline-block; transform: rotate(180deg)">31</span> (a turned 31). If the base note is C, then 31/16 is represented by C–B31.
