Inversion (music)

Reversal is called in music:

  • At a melodic line a mirror, so swapping the pitch movement ( mirrors on the horizontal), often found in counterpoint ( Spiegelfuge ), especially canon and fugue, and in the twelve-tone ( the reflection in a vertical axis called cancer);
  • The intervallic inversion;
  • A chord whose bass note (lowest note ) does not coincide with the root, for example, a sixth chord ( " first inversion ") or a six-four chord ( " second inversion ").
