Rasarnavasudhakara 1.428

Evenness of crisp structure [sphuṭa-bandha-samatā] is as follows:
“By the sweet female bee, whose wit was nurtured
by the profusion of honey from the mādhavī awakened by spring,
a song was sung repeatedly, with distinct syllables
carrying an intoxicating hum.”

[Māgha, Śiśupālavadha 6.20]

Here, because a diction predominantly composed of crisp phonemes is maintained throughout, there is evenness of crisp structure.

Evenness of mixed structure [miśra-bandha-samatā] is as in the verse beginning “Both blossoming cheeks” [Kumārasambhava 3.4], and so forth. Here, because a diction mixing soft and crisp phonemes is maintained, there is evenness of mixed structure.
