A minor chord is characterized by its melancholic and somber sound, distinguishing it from the brighter and more uplifting major chord. The basic structure of a minor chord is formed by combining three notes: the root note, a minor third, and a perfect fifth. This creates a distinctive tonal quality that is both rich and expressive. In music theory, the minor third interval plays a crucial role in defining the chord's emotional tone. For guitarists, the minor chord is one of the most fundamental and frequently used chord qualities across a wide array of musical genres, from rock and pop to jazz and classical music.
