c major chord - Parker Core Knowledge

Understanding the Context

In music theory, the C major chord is a triad consisting of three notes:
C (the root), E, and G.
These notes are built from the first, third, and fifth scale degrees of the C major scale (C – D – E – F – G – A – B – C).

Because all three notes are on the C major scale, they create a harmonious and consonant sound that naturally resolves well within most musical contexts.
