Which mode is defined as a minor scale with a natural 6?

The Dorian mode is characterized as a minor scale that includes a natural sixth scale degree. This defining feature differentiates the Dorian mode from other minor modes. In the context of the Dorian scale, it can be described as a natural minor scale with an added raised sixth, leading to a unique sound and feel. For example, if you take the D Dorian mode, the notes would be D, E, F, G, A, B, and C, which clearly illustrates the natural sixth (B).

The presence of the natural sixth contributes to a brighter quality compared to other minor modes, especially when compared to the Aeolian mode, where the sixth is lowered. This alteration allows for a different harmonic and melodic approach in music creation and improvisation. The Dorian mode is often used in various styles, including jazz, rock, and folk, because of its versatile and distinct character, making it a valuable tool for musicians.
