Modal music refers to a style of music that is based on modes, which are specific scales that create different moods and feelings. Unlike traditional Western music that primarily uses major and minor scales, modal music employs a variety of modes, such as Dorian, Phrygian, and Mixolydian. This approach allows for a broader range of emotional expression and tonal color. Historically, modal music has roots in ancient Greek music and was prominent during the Medieval and Renaissance periods. It has influenced various genres, including jazz, folk, and even some forms of rock music. Composers like Béla Bartók and Debussy have incorporated modal elements into their works, showcasing its versatility and enduring appeal.
