The Lydian Dominant scale is a musical scale derived from the traditional Lydian mode, commonly used in jazz, fusion, and various genres of modern music. Also known as the Overtone Major scale or the Lydian b7 scale, it is built by raising the fourth degree of the major scale, starting on the root note, a perfect fourth above it. In terms of intervals, the scale contains a major third, perfect fourth, perfect fifth, major sixth, minor seventh, and major second.
The standout characteristic of the Lydian Dominant scale is the presence of the flat seventh (b7) in comparison to the Lydian mode. This flattened seventh creates a feeling of tension, allowing musicians to explore a more dynamic and expressive tonal palette. The scale's name "Lydian Dominant" is derived from the dominant seventh chord created from this scale's root note.
The Lydian Dominant scale is often used to add color and extend harmonies in chord progressions by providing a sense of tension and release. It is frequently employed over dominant chords and altered dominant chords, enabling musicians to create a chromatic and adventurous sound. Due to its unique combination of intervals, the Lydian Dominant scale offers a rich and exotic flavor to musical compositions.
In summary, the Lydian Dominant scale is a versatile and expressive musical scale, renowned for its use in jazz and other contemporary genres. Its flattened seventh degree adds tension and character to harmonic progressions, allowing musicians to explore a wide range of creative possibilities.
