Pivot chords

Definition

Pivot chords are chords that serve as a common link between two different keys, allowing for smooth modulation from one key to another. They act as a bridge during transitions in harmonic progressions, making the shift between keys more seamless and musically coherent. By utilizing pivot chords, musicians can enhance their improvisation and create more dynamic harmonic landscapes.
