This article will guide you through everything you need to know about the G Major Guitar Scale, from its notes and intervals to practical positions and exercises.
Understanding the G Major Scale Notes and Intervals
The G Major scale consists of seven notes: G, A, B, C, D, E, and F#. These notes follow a specific pattern of whole and half steps, often represented as 2 – 2 – 1 – 2 – 2 – 2 – 1 (where 2 represents a whole step and 1 represents a half step). This formula is consistent for all major scales, making it a valuable concept to memorize.
The intervals within the G Major scale, starting from the root note G, are as follows:
| Formula | Notes | Intervals | Degrees |
|---|---|---|---|
| 1 | G | Unison | Tonic |
| 2 | A | Major second | Supertonic |
| 3 | B | Major third | Mediant |
| 4 | C | Perfect fourth | Subdominant |
| 5 | D | Perfect fifth | Dominant |
| 6 | E | Major sixth | Submediant |
| 7 | F# | Major seventh | Leading Tone |
This table breaks down the scale degrees, providing a theoretical understanding of each note’s function within the G Major scale.
