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.

Theoretical construction

Major chord is Western harmony's cornerstone. Formula 1 - 3 - 5: root, major third (4 semitones), perfect fifth (7 semitones).

Example C major: C - E - G. Major third (C-E) + minor third (E-G) creates characteristic bright sound.

Acoustically, frequencies form simple ratio (4:5:6), explaining natural consonance and "stable", "cheerful" perception.
