Which of the following is true of cadence? Select all that apply. A. Cadence is a kind of rhythm
B. Cadence is not completely regular
C. Cadence is a rhythmical pattern
D. Cadence is required for every poem

A. I think because Cadence, in music, the ending of a phrase, perceived as a rhythmic or melodic articulation or a harmonic change or all of these; in a larger sense, a cadence may be a demarcation of a half-phrase, of a section of music, or of an entire movement. (I am sorry if I am wrong )
