A major chord is a type of musical chord that consists of three specific notes: the root, the major third, and the perfect fifth. For example, in the C major chord, the notes are C (the root), E (the major third), and G (the perfect fifth). Major chords are often described as having a bright, happy sound and are commonly used in various music genres. In music theory, major chords are built on the first, third, and fifth degrees of the major scale. They are fundamental to creating harmony and are frequently used in songs to establish a sense of resolution and positivity. Understanding major chords is essential for musicians and composers when crafting melodies and harmonies.
