A natural minor scale is a seven-note scale that follows a specific pattern of whole and half steps. The sequence of intervals is: whole, half, whole, whole, half, whole, whole. This scale is often used in various music genres, providing a darker or more somber sound compared to its major counterpart. In the key of A minor, for example, the notes are A, B, C, D, E, F, and G. The natural minor scale is essential for understanding music theory and composition, as it serves as a foundation for creating melodies and harmonies in minor keys.
