The major scale formula
Concept
The major scale is built from a single pattern of whole and half steps: W-W-H-W-W-W-H. Start on any note, follow that pattern, and you get a major scale.
The formula in detail
Starting from any note, count: whole, whole, half, whole, whole, whole, half. That's 7 notes (the 8th is the octave).
In C: C (W) D (W) E (H) F (W) G (W) A (W) B (H) C. In G: G (W) A (W) B (H) C (W) D (W) E (W) F# (H) G — the F# appears because B→C is already a half step, so the next whole step has to land on F#.
Why C is the 'easy' key
C major contains no sharps or flats — only the natural letters A through G. It's the only major key with that property. Every other major key adds at least one sharp or flat to satisfy the W-W-H-W-W-W-H pattern.
Scale shapes on guitar
Because the pattern is fixed, the FINGERING shape of a major scale starting on the 6th string is the same for every key — you just slide it. Learn one shape, get all 12 keys for free.
Key takeaways
- •W-W-H-W-W-W-H. Memorize it.
- •C major = all natural notes. Every other key adds accidentals.
- •One fingering shape moves all 12 major keys around the neck.
Glossary
- Leading tone
- The 7th scale degree. It pulls strongly up to the tonic.
- Accidental
- A sharp, flat, or natural that adjusts a note outside the key signature.
