Major chord - guitar
The major chord is a triad composed of three notes: a root, a major third and a perfect fifth. This structure produces a stable and consonant sound, widely used in all musical styles.
Intervals
| Degree | I | III | V |
|---|---|---|---|
| Interval | Root | Major third | Perfect fifth |
| Semitones | 0 | 4 | 7 |
Formula 1 - 3 - 5
Theory
The major chord is built by stacking two thirds: a major third (4 semitones) followed by a minor third (3 semitones). This stacking creates a perfect fifth interval (7 semitones) between the root and the fifth. The 1-3-5 formula is universal: C major = C-E-G, D major = D-F♯-A, etc.
