It’s built upon the root note G and follows a specific interval pattern: Whole, Whole, Half, Whole, Whole, Whole, Half (W-W-H-W-W-W-H). This pattern defines the characteristic major sound and is consistent across all major scales, only starting on a different root note.
The notes of the G Major scale are: G – A – B – C – D – E – F#. Notice the F sharp (#) – this is crucial for creating the major tonality.
The intervals within the G Major scale from the root (G) are:
- Major Second (M2): G to A
- Major Third (M3): G to B
- Perfect Fourth (P4): G to C
- Perfect Fifth (P5): G to D
- Major Sixth (M6): G to E
- Major Seventh (M7): G to F#
Understanding these notes and intervals is key to truly grasping the G Major scale and its application in music.
