In
Western musical theory, a
harmonic cadence (Latin
cadentia, "a falling") is a
progression of (at least) two
chords that
concludes a
phrase,
section, or
piece of
music.
[1] A
rhythmic cadence is a characteristic
rhythmic pattern indicating the end of a phrase.
[2] Cadences give phrases a distinctive ending that can, for example, indicate to the listener whether the piece is to be continued or concluded. An analogy may be made with
punctuation,
[3] with some weaker cadences acting as commas that indicate a pause or momentary rest, while a stronger cadence acts as a period that signals the end of the phrase or
sentence. A cadence is labeled more or less "weak" or "strong" depending on the sense of finality it creates. While cadences are usually classified by specific
chord or
melodic progressions, the use of such progressions does not necessarily constitute a cadence—there must be a sense of closure, as at the end of a phrase. - wikipedia
Not sure where I got this next one.
Cadencia - A deep check and replace, usually led by the man as he steps forward left. Useful for avoiding collisions and making direction changes in small spaces. May also refer to a subtle shifting of weight from foot to foot in place and in time with the music done by the man before beginning a dance to give the lady the rhythm he intends to dance and to ensure that she will begin with him on the correct foot.
