Compared to major scales and chords, minor scales and chords have different 3rds. Similarly, most chords and arpeggios usually contain 3 or 4 different notes like a Root, 3rd, and 5th (triads), or a Root, 3rd, 5th, and 7th (seventh chords).Īll of these scales and chords contain that important note the 3rd in them. For example, the major scale contains a Root, 2nd, 3rd, 4th, 5th, 6th, and 7th. If you’ve spent any time studying a few scales you should know many scales contain seven different notes. The third is what gives major-sounding scales and chords their brighter, cheerier sound, and what gives minor scales and chords their darker, sadder sound.

The difference between major and minor chords and scales boils down to a difference of one essential note the third. I hear this question from beginning students all of the time: What Is the Difference Between Major and Minor?
