'''36:45:54:64''' | {{Nowrap|'''36:45:54:64'''}}, the ''Ptolemaic dominant seventh chord'', is a [[dominant seventh chord]] found on the dominant scale degree ([[3/2]] or V) of Ptolemy's intense diatonic scale ([[Zarlino]]), perhaps the most common 5-limit diatonic. It combines a [[5/4]] major third with a [[16/9]] Pythagorean minor seventh, creating a [[64/45]] tritone between the two. | ||
