Music Theory/Chords. This is a basic introduction to chords. There is also a complete chord reference. Chords are the vertical arrangement of notes from a scale. The study of chords is called Harmony. Harmony is concerned with how one or more notes interact, and how they follow each other.
The formula for major chords is 1 3 5. That means if we want to know how to make the chord of C major, we would take the 1st, 3rd & 5th notes of the C major scale. Similarly, if we wanted to build the chord of G major, we would use the 1st, 3rd & 5th notes of the G major scale. Let's take a closer look at both the scale and chord of C major.
