Chord of the Month
Why do first time dabblers at the keyboard always go for the black notes? Every one of them? Mainly because any arrangement of them sounds okay... pleasant... concordant... nice. Anyway, so as to make you feel at home, something simple to kick off with. Could be "Drive" by the Cars, or a host of other tune fragments. A neat little movement - major chord, shifting to major seventh.
B bass - ordinary B major chord (1st inv)
B bass - B major seventh chord
