Lesson transcript

Dominant Ninth Chords

So now we're going to move on to dominant ninth chords.

Understanding the Ninth

  • Starting with a C7:
    • The ninth is the same note as the second of the scale.
    • But you can't play those five notes with one hand.

If you take the root away, you end up with what looks like:

  • E half diminished
  • E minor 7, flat 5

And the C might be down in the bass.

Chord Shapes and Ambiguity

These shapes are ambiguous. If you didn't know there was a C in the bass, you'd think that was E minor 7, B5.

But you might be playing C7 in the left hand and an arpeggio (3, 5, 7, 9) in the right hand.

Differences in Chords

The difference between this and the major nine is the flat seven:

  • We have a B flat now.

Applying the Chord Shapes

We can use this now when we play chord shapes as well:

  • G minor 7, third inversion:
    • Remember, you just move one note: the F goes down to E, and that becomes C9.

You could do it down here as well with G minor 7:

  • I've taken the G out because it's in the bass.
  • Move the F to an E, and that gives us C9.

Simplifying the Process

You don't even have to understand that to do it; just moving one note works. Of course, I'm moving the bass as well.

But even without the bass, you get the 2,5 sound.

Next Steps

And we're going to use that in our next tune, Funky 2 5.

Tim Richards

Critically acclaimed jazz pianist and composer Tim Richards is one of Britain’s most experienced jazz educators, teaching piano privately for over 30 years, as well as at Morley College, Goldsmiths College, the University of Surrey, Premises Studios and other venues in the UK and abroad. He has produced numerous titles for Schott Music, including the best-selling two-volume Exploring Jazz PianoBlues, Boogie & Gospel Collection and the acclaimed Improvising Blues Piano. He is also co-author, with John Crawford, of Exploring Latin Piano and Brazilian Piano Collection.

“The real joy of Tim’s music… is that it is both hugely educational but also such great fun to play. Anyone with the slightest interest in learning to play or teach jazz piano should really acquire a set of Tim’s books.” PianoDao

His latest recording, the album ‘Telegraph Hill’ by the six-piece Hextet, was described in The Observer as "A true joy from beginning to end".
