How Music Notes Work Together

Unisons, Intervals, and Chords


     A unison is a single note, whereas an interval consists of 2 notes of different pitches:

    Intervals occur in 5 classes:

  • Major intervals

  • Minor intervals

  • Diminished intervals

  • Augmented intervals

  • Perfect intervals

     When inverted (turned upside down):

  • A major interval becomes a minor interval
  • A minor intervals becomes a major interval
  • An augmented interval becomes a diminished interval
  • A diminished interval becomes an augmented interval
  • A perfect interval becomes a perfect interval
