Kadence

Kadence is a spelling variation of Cadence, the English word connected with rhythm and the flow of sound. In music, a cadence can describe the closing movement of a phrase, while everyday speech also has a cadence. That gives the name a more specific musical and spoken-language background than the broad idea of a beat alone.

Changing the initial C to K keeps the intended sound while distinguishing the written name. Cadence preserves the standard dictionary spelling, whereas Kadence is a modern personal-name adaptation. Its resemblance to Kaden does not establish the same origin: the defining connection is with the musical word. The full name works independently without needing a longer formal version.
