A minor chord on the piano is a triad, a three-note chord, constructed with a root, a minor third, and a perfect fifth. For example, the A minor chord consists of the notes A, C, and E. This specific interval arrangement distinguishes it from a major chord, which utilizes a major third interval. Mastering this fundamental chord structure unlocks a broad palette of musical expression.
The ability to play minor chords is crucial for understanding and performing a vast repertoire of musical pieces across diverse genres. Minor keys and chords are frequently employed to evoke emotions such as sadness, introspection, or mystery, adding depth and complexity to musical compositions. Understanding their construction allows for informed improvisation and composition.
