How important are major chords? Since probably 80% to 85% of all the chords used in music are some form of major chords, I’d say they are pretty important. And since there are only 12 of them (not counting enharmonic chords like Gb and F#) it’s not too much to go to the trouble of learning them.

Three of the major chords are composed of just white keys on the piano; three major chords have a black key as the 3rd of the chord; three major chords are like Oreo cookies; one major chord is composed of all black keys; and two are left over — B and Bb.
