What is a diatonic major scale?

A diatonic major scale is a seven-note musical scale that follows a specific pattern of whole steps (W) and half steps (H). It is a fundamental scale in Western music and forms the basis for constructing major keys.

The pattern for a diatonic major scale is as follows:

W – W – H – W – W – W – H

To illustrate this pattern, let’s take the C major scale as an example:

C – D – E – F – G – A – B – C

In this scale, you can see that the intervals between the notes follow the pattern of whole steps (W) and half steps (H). For example, the interval between C and D is a whole step (W), between D and E is a whole step (W), between E and F is a half step (H), and so on.

It’s important to note that the diatonic major scale always follows this pattern, regardless of the starting note. By applying the same pattern starting from any other note, you can construct the major scale in different keys.

The diatonic major scale is widely used in Western music and forms the basis for melodies, harmonies, chords, and key signatures. It has a bright and uplifting sound and is often associated with happy or joyful music.
