Sequence


Definition:

  • (n.) The state of being sequent; succession; order of following; arrangement.
  • (n.) That which follows or succeeds as an effect; sequel; consequence; result.
  • (n.) Simple succession, or the coming after in time, without asserting or implying causative energy; as, the reactions of chemical agents may be conceived as merely invariable sequences.
  • (n.) Any succession of chords (or harmonic phrase) rising or falling by the regular diatonic degrees in the same scale; a succession of similar harmonic steps.
  • (n.) A melodic phrase or passage successively repeated one tone higher; a rosalia.

  • (n.) Three or more cards of the same suit in immediately consecutive order of value; as, ace, king, and queen; or knave, ten, nine, and eight.
  • (n.) All five cards, of a hand, in consecutive order as to value, but not necessarily of the same suit; when of one suit, it is called a sequence flush.

Example Sentences:
