Modal scales are a type of musical scale that are derived from the seven modes of the major scale. Each mode has a unique pattern of whole and half steps, which gives it a distinct sound. The seven modes include Ionian, Dorian, Phrygian, Lydian, Mixolydian, Aeolian, and Locrian. Musicians often use these scales to create different moods and atmospheres in their compositions. Each modal scale starts on a different note of the major scale, altering the sequence of intervals. For example, the Dorian mode has a minor third and a major sixth, while the Lydian mode features a raised fourth. This variety allows composers and improvisers to explore diverse musical expressions beyond traditional major and minor scales.
