What is a music chord?
A chord in music is any harmony of two or more unique notes. In western music, we tend to focus on chords comprised of three unique notes characterized as a triad. The three notes are the root note plus the third and fifth intervals above the root in a diatonic scale of the key of the desired chord. For instance, if we are creating a C Major Chord, we will use the root (C), the third interval (E), and the fifth interval (G) in the C Major scale.
