Welcome to Music Modulation.
Tonality does not exist in absolute terms, it manifests itself through a harmonic movement where the chords have relationships with each other. Relationships of tension or relaxation around a central chord called Tonic. A Tonality can be defined by the key signature.
Moving from one key (Tonality) to another one is called, Modulation.
- Direct Modulation. (moving directly from one key to another)
- Using transition chords (V7), "dominant 7th chords" See Chords lll page.
- Using Pivot chords and Pivot notes. (yet to come)
