alone may not capture their cadence.","In a musical closure sense, cadence concerns an ending's organisation and effect; tempo concerns how quickly the music proceeds.","Movement cadence counts defined actions per unit time and does not determine travel speed without information such as distance per action.","A scheduled repetition is an intended cadence; evidence of actual occurrences is
