Harmonic Minor Key

Definition

The harmonic minor key is a musical scale that differs from the natural minor scale by raising the seventh note, creating a leading tone that enhances the harmonic and melodic function. This alteration provides a stronger resolution to the tonic, making it particularly effective in establishing a sense of tension and release in music. The harmonic minor key is often used in various genres to evoke emotional depth and complexity.
