All the 9th Chords
How to Handle Five-Finger Chords
Hello again, and welcome to the next lesson . I hope you are enjoying learning about all the chords in the world -- and we're going to cover them ALL before we're done -- you'll know more about chords than 99% of the people in the world -- believe it or not, it's true.
Last time we covered maj7th chords. That was the last of the chords you can play without doing some fancy manuvering. Today we're going to learn 9th chords, and from now on we will be inverting the chords and using a 2-step process to play the chords.
A 9th chord is made up of a root, a 3rd, a 5th, a 7th (not the maj7th -- just the 7th) plus the 9th note of the scale, which of course is the same as the 2nd note of the scale, but an octave higher.
Why don't we call it a "2nd," then, instead of a 9th? Because the chord has a 7th under the 9th, whereas a 2nd wouldn't have a 7th under it. So:
9th Chord = Root - 3rd - 5th - 7th - 9th
Add the 9th note of the scale to the 4-note 7th chord -- therefore we have a 5-note chord. NOTE: the PSR-2000 accompaniment will recognize a 9th chord. if you key the Root + 2nd + 3rd + 5th -- you can omit the 7th, i.e. C - D - E - G = C9
What's the problem with a 5-note chord? Nothing, except if your hand is small like mine. I can't reach all 5 keys, so I had to come up with another way to position the chord on the keyboard. (And even if your hand is big enough to reach a 9th, you won't have enough fingers to play an 11th or 13th! So you have to come up with a way to play those humungous chords, and this is the best way I've found -- though not the only way.)
What we do is this: Get your left hand in 2nd inversion on the piano keyboard like this (we'll use the C chord to illustrate):
Then add the 7th to the chord:
Now take your index finger off "C" and play "D" instead, like this:
You may be saying "But how could that be a C9 chord? It doesn't have a C in it!"
And you would be right.
So what we need to do is to play the C -- the root of the chord -- an octave below middle C while we depress the sustain pedal, and then play the chord shown above.
| Step 1: || Step 2 |
The sustain pedal hooks the two parts together to make one cohesive chord -- a C9.
So if you want to play a F9 chord, you would play a low F (the root of the F chord) low on the keyboard, then play the F9 chord while the sustain pedal is depressed. Same for any other 9th chord -- play the low root, then the chord.
Here's what 9th chords look like on the staff: (Remember that accidentals carry over in the same measure!)
A major, minor or dominant ninth chord
adds a 9th--major unless otherwise indicated--above the root of a major, minor or dominant seventh chord. A flattened ninth chord adds a flatted 9th above the root of a dominant 7th chord. These chords ordinarily appear in leadsheets as the following chord symbols:
CMA9 C9 Cm9 C7(b9)*
* In jazz and popular music, when the 9th is altered, the 7th is always included in the chord symbol.
PSR Note: The PSR-2000 will recognize C-D-E-G-Bb as the C9th chord. The G note is optional. C-D-E-Bb would also be recognized as C9th so you can play this chord with 4 fingers. In fact, you can play the chord with only 3 fingers since you can also drop the "C", but only if you are playing E-Bb-D. (D-E-Bb won't work.) How do you remember that particular combination. Easy. Play C7 in the 2nd inversion (E-G-Bb-C). Now, to play the 9th, just move your thumb up one key from the C to the D and, at the same time lift your finger up from the 2nd note (G). You are now playing E-Bb-D = C9th. This will work with any chord. Play the 7th with the root on top, move your thumb up one step and lift your 2nd finger and the PSR-2000 will be playing the 9th and you are using only 3 fingers! (Thanks to Scott Langholff for the E-Bb-D tip.) - Joe WatersAnd here's what they look like when played with your left hand on the keyboard: (But don't forget: you MUST play a low note (the root of the chord) before you play the chord, then hook them together with your sustain pedal!)
You may be wondering if you can play 9th chords in different inversions, like you can invert 6th and 7th chords. The answer is "sure" -- but if I were you I would master one inversion before trying to use several different ones. When you're dealing with this many chords, it's easy to get turned around and confused. So unless you have a very good reason to use a different inversion, I would stick with only one inversion for now.
As usual, now it's up to you. Play each 9th chord in root position, then 1st inversion, then 2nd inversion, then in 3rd inversion (the maj7th will be the lowest note of the chord) Play each chord up and down the keyboard for at least 2 octaves -- maybe 3 octaves. Play them with your left hand, then play them with your right hand. Then play them hands together. Go through all 12 major chords, inverting every one. Then go through all the 12 minor chords, inverting each one up and down the keyboard -- hands alone, then hands together. Then go through all 12 diminished chords, inverting each one up and down the keyboard -- each hand alone, then together. Then play the 12 augmented chords, up and down the keyboard. Then skip around from major to minor to diminished to augmented, etc. Then add minor 6th chords to your repertoire of chords. They are shown in root position above, but you know that you can turn them upside down 'till the cows come home -- invert them -- so go to it! And then add 7th chords and their inversions....then add the maj7th chords we've learned last lesson Then finally, add these 9th chords into the mix -- but don't forget to play the low root before playing the chord -- that's a must! Do you feel like you're getting a handle on chords yet? You ought to -- I know we're going slowly, but chords are SO important that you absolutely MUST master them if you are ever going to play the piano like you hope to! So here's our revised chord scorecard:
12 major + 12 minor + 12 diminished +
12 augmented + 12 major 6th + 12 minor 6th +
12 7th + 12 maj7th and 3 or 4 inversions
of each and now, Twelve 9th chords
which means you can now play
Yea! Three cheers for you!
Next lesson we will add 12 more chords to our growing list of chords we can play by adding 11th chords to our stash.
