Musical Keys - XML

Musical keys are essential elements that determine the scalar foundation and mood of a piece of music. Major keys have a bright and open sound, while minor keys have a dark and introspective quality. Following the circle of fifths, there are 12 major keys and corresponding 12 minor keys, each with different key signatures. These keys provide a fundamental framework for composition and performance in Western music.
