Another common chord or triad is the minor chord. You know you have heard a minor chord when the chord sounded mellow and even a bit sad. A majority of the music from the Asian world is composed in the minor key, which gives a unique flavor, sometimes associated with Asia and nostalgic feelings.
You too can build a minor chord using a specific formula, 3+4 semitone. Some of the most impressive classical music was composed in the minor key such as the Pathetique sonata by Beethoven, composed in the key of C minor.

 

 

Little did I know the importance of piano chords inversions when I first studied music theory back in the old days. I thought it was just a bunch of musical notes rearranged in different orders. As I started to understand a bit more about improvising, composing and music arrangement, I started to experiment with various chords inversions and got to fully understand the role of chords in piano playing.

Piano chords are the building blocks of music. They're also a shortcut to understanding overall music playing.
