A diatonic scale is a seven-note musical scale that consists of five whole steps and two half steps. The most common diatonic scales are the major scale and the natural minor scale. Each scale has a unique pattern of intervals, which gives it a distinct sound and character. Diatonic scales form the foundation for much of Western music, influencing harmony and melody. They are used in various genres, from classical to pop, and serve as the basis for constructing chords and harmonies. Understanding diatonic scales is essential for musicians and composers.
