From low to high, we have: Root (C) - dominant 7th (Bb) - 9th (D) - 11th (F). Again, the 5th is omitted, which helps with fingering on the guitar, but it’s also common practice to stop chords ...
All the chords built on other notes in the scale of C are minor, except chord VII - the notes B – D – F, which is diminished. When a seventh is added to a chord this is known as a seventh chord.
