pivotchordmodulaatio

Pivotchordmodulaatio is a musical term referring to a specific type of chord modulation, or key change, within a musical composition. It is characterized by the use of a pivot chord, which is a chord that is common to both the original key and the new key. This shared chord acts as a bridge, facilitating a smooth transition between the two harmonic areas.

The effectiveness of a pivot chord lies in its ability to exist functionally in both keys. For instance, a dominant chord in the new key might also be a secondary dominant or a subdominant chord in the original key. This commonality allows the listener's ear to accept the shift in tonality without experiencing an abrupt or jarring change. By reinterpreting the function of the pivot chord within the new harmonic context, the composer guides the listener into the new key.

Pivot chord modulation is a widely used technique across various musical genres due to its versatility and natural sound. It allows composers to introduce harmonic variety and emotional depth to their music by moving to related keys, such as the dominant, subdominant, or relative major/minor. The choice of pivot chord and the resulting key are crucial elements in the overall harmonic structure and narrative of a piece.
