Hi Tom. With all the II-V7 1 chord voicings provided for in great detail above, you should easily be able to make a chord comparison test yourself on your KN5000
Begin by selecting the piano sound (RT1), playing (in full keyboard mode) with the auto accomp arranger function turned OFF.
Now, play with your left hand (in the octave just below middle C) a standard II - V7 - I chord progression in the key of C (voiced like this):
Dm7 - G7 - C
(D-F-A-C) - (D-F-G-B) - (E-G-C)
now play the SAME progression but voiced this way:
Dm79 - G13 - C69
(F-C-E) - (F-B-E) (E-A-D)
You will notice that the first way sounds consonant and pure (defined) while the second method sounds more open and less defined. Played without any accompaniment, the first method probably sounds much more satisfying to the ears. The second way may sound awful to some ears. Hold on, stay with me. Please don't give up on me yet.
Now (in full keyboard mode), select the medium tempo swing style:'Jazz Trio' and mute all accompaniment tracks except drums, acoustic bass & Piano (RT1) part. Set the tempo at around 120 or slower. Play the SAME two chord progressions (one measure for 1st two chords and 2 measures for last chord: total=4 bars) With the now added accomp parts, you may notice that the second version (rootless chords) begins to sound better and more interesting. If you turn UP the Bass auto-accompaniment part, you will notice that "IT" is the instrument now providing the chord root notes (the foundation of the harmonies) in the walking bass pattern it plays. The 3 note piano voicings are now free to supply the chord tensions (9th, 6th, 13th) while the bass is playing the foundation of the chords (roots).
Now, go back and play the chord progressions with your left hand (both above versions) with auto accomp still turned ON, and solo over the chord changes with the right hand. You will notice that there is a big difference in the sound. The first method sounds good yet basic (like vanilla, chocolate) but the second method sounds more open, yet complex (ethereal rasberry vanilla with chocolate chip & almonds). This opens up your right hand soloing options to more possibilities. Because the keyboard rootless type comping chords do not include the root, this keeps the harmonies more undefined and opens up the right hand to go in more directions. This in turn provides us (as musicians) a wider palette of colors to choose from when expressing ourselves (soloing) over the chord changes.
I hope this helps. - Scott
http://scottyee.com PS: Also try the below two handed comping chords and compare the first version (basic but good) to the second version. The second version, with the wider more open chord voicing and the added 13th (6th) note (D), adds another subtle flavor (spice) to the mix and results in slightly more complex sound. As a musician, you are like a chef, able to add/remove spices as needed to enhance your creation. The TRICK is what spices to use and in what quantities. That's in another story.
The bottom line is to experment and have FUN !
version 1:
(F-A-Eb) - (G-C-F): F79
left hand - right hand
version 2:
(Eb-A-D) - (G-C-F): F13
left hand - right hand
