The universality and innate nature of music, and the pentatonic scale, as demonstrated by singer Bobby McFerrin.
In Western music, the primary difference between major and minor scales lies in the specific sequence of whole steps (tones) and half steps (semitones) used to construct the octave.12
Interval Structures
The two scales are defined by the following patterns:
- Major Scale: Follows the sequence of whole step, whole step, half step, whole step, whole step, whole step, half step (W–W–H–W–W–W–H).32
- Natural Minor Scale: Follows the sequence of whole step, half step, whole step, whole step, half step, whole step, whole step (W–H–W–W–H–W–W).12
Variations and Characteristics
While the major scale maintains a consistent structure, the minor scale is frequently altered to create different musical effects. These variations include:12
- Harmonic Minor: The seventh tone of the natural minor scale is raised by a half step.12
- Melodic Minor: The sixth and seventh tones are raised by a half step when ascending, but remain unaltered when descending.12
In modern music theory, major and minor scales are often related through parallel keys (sharing the same tonic) or relative keys (sharing the same key signature).1
