Cadence (emphasis on "e") is a multi-valued word. In music, it means a loss from several notes, repeated at the end of each musical phrase.
In politics, the term "cadence" sometimes refers to the period of authority of an official or a whole government. In this sense, it is synonymous with the term "time". For example: Putin's fourth cadence is already an overt search.
The Latin root "cadere", from which the word "cadence" occurs, can be translated as "fall, fall out." In this sense, both the musical and political significance of the given word is reduced to something that falls out once in a certain period.
