What is the defining feature of modal jazz that distinguishes it from other jazz forms?

The defining feature of modal jazz that distinguishes it from other jazz forms is its emphasis on modal scales. Unlike traditional jazz, which often relies heavily on complex chord progressions, modal jazz prioritizes the use of scales, or modes, as a basis for improvisation and composition. This approach allows musicians to explore a wider range of melodic possibilities within a more stable harmonic environment. By focusing on modes rather than constantly changing chords, artists have the opportunity to create a more fluid and expansive musical expression.

Traditional chord progressions, fast tempo, or a focus solely on instrumental improvisation do not encapsulate the essence of modal jazz. These elements may be present in various forms of jazz but are not exclusive to or defining for modal jazz. The focus on modal scales creates a unique character and sound that set modal jazz apart from other jazz styles, influencing countless artists and compositions since its emergence.
