What's the difference between sequence and variant?

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.) A hymn introduced in the Mass on certain festival days, and recited or sung immediately before the gospel, and after the gradual or introit, whence the name.
  • (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.

Variant


Definition:

  • (a.) Varying in from, character, or the like; variable; different; diverse.
  • (a.) Changeable; changing; fickle.
  • (n.) Something which differs in form from another thing, though really the same; as, a variant from a type in natural history; a variant of a story or a word.
