Music Theory: Major Chords

Major Chords

• Major chords are musical chords built on the principle of consonant interval relationships.
• The defining characteristic of a major chord is the major third built on the root.
• A major chord consists of three notes: the root, major third, and perfect fifth.

Construction of Major Chords

• The intervals within a major chord are:
  • root to major third
  • major third to perfect fifth
• The root is the first note of the chord, forming its basis.
• The major third creates a bright and consonant sound relative to the root.
• The perfect fifth completes the triad, providing a stable and consonant interval above the major third.

Common Major Chords

• C major chord (C-E-G)
• G major chord (G-B-D)
• D major chord (D-F#-A)
• A major chord (A-C#-E)
• E major chord (E-G#-B)
• B major chord (B-D#-F#)
• F# major chord (F#-A#-C#)
• C# major chord (C#-E#-G#)

Inversions of Major Chords

• A major chord can be inverted by putting any note (except the root) in the lowest position.
• First inversion: The major third is in the bass.
• Second inversion: The perfect fifth is in the bass.

Major Chords in Music Theory and Practice

• Understanding major chords is crucial for harmony in composing, arranging, and playing music.

Major Chords and Key Signatures

• Each major key has its own set of major chords.

Applications in Music

• Major chords are frequently used across musical genres for their bright and uplifting sound.
• They often evoke feelings of joy, peace, or optimism in music.
