Scales

The harmonic minor scale is a seven‑note minor scale distinguished by a raised seventh degree, creating a leading tone to the tonic. It is a foundational element in Western classical, jazz, and metal music.

The blues scale is a six‑note (hexatonic) scale derived from the minor pentatonic with an added flattened fifth, creating the characteristic “blue” sound used in blues, jazz, rock, and many other styles.

The diatonic scale is a seven‑note musical scale consisting of five whole steps and two half steps in a fixed pattern, forming the basis of most Western tonal music.

The major scale is a seven‑note diatonic scale characterized by a specific pattern of whole and half steps, forming the basis of much Western tonal music.
