Major scale

Major scales beginning with white keys

The pattern of whole and half steps characteristic of a major scale

Major scale refers to a scale in Western music that is one of the most commonly used musical scales, especially in classical, jazz, and many types of popular music. The major scale is made up of seven distinct pitches, plus an eighth that duplicates the first an octave higher. The sequence of intervals between the notes of a major scale is whole step, whole step, half step, whole step, whole step, whole step, half step.

Structure

The major scale is constructed from a series of whole steps and half steps in the following sequence: W-W-H-W-W-W-H, where "W" stands for whole step and "H" for half step. In the context of a piano keyboard, a whole step means skipping one key (whether black or white), and a half step means moving to the next key directly without skipping.

For example, the C major scale, which is the most commonly used example due to its lack of sharp and flat notes, consists of the notes C, D, E, F, G, A, B, C. Starting from C, there are whole steps between C and D, D and E, then a half step between E and F, followed by whole steps between F and G, G and A, A and B, and finally a half step from B back to C.

Modes

The major scale forms the basis of several musical modes, which are scales derived from the major scale by starting on a different note but using the same sequence of whole and half steps. The modes of the major scale include the Ionian mode (which is the major scale itself), Dorian, Phrygian, Lydian, Mixolydian, Aeolian (or natural minor scale), and Locrian.

Harmony

The major scale also plays a crucial role in the formation of chords and harmony in Western music. The triads (three-note chords) built on each degree of the major scale have specific qualities (major, minor, diminished) that form the foundation of harmonic progressions in many musical traditions.

Transposition

The major scale can be transposed to any starting note, resulting in 12 different major scales—one for each note in the chromatic scale. Each scale has its own unique set of sharp or flat notes, except for the C major scale, which has none.

In Music Education

The major scale is often one of the first scales taught in music education due to its fundamental role in music theory, harmony, and ear training. Understanding and being able to play or sing major scales is considered essential for developing musicians.

Cultural Significance

The major scale is often associated with happy and bright emotions, in contrast to the minor scale, which is typically associated with sadder or more somber emotions. This association, however, can vary significantly across different cultures and musical contexts.
