How are these chords constructed? and when would you use them in a jazz progression?
Why would you use this chord instead of a 6th or a 9th

Constructed 1 3 5 6 9
So: C6/9 has C E G A D,
Cmin6/9 has C Eb G A D
I used them for the sake of variety, instead (or alternating) with other major/minor chords. If the root is in the melody, you might want to avoid playing a CMaj7, for example, and play a C6 or C6/9 instead.
They may also make sense for voice leading reasons, but if you're looking for a deep reason to use them, as opposed to a 6th or 9th chord, I don't know of one, but I'm more of an ear guy than a theory guy.
EDIT: you can also stack up the notes for a quartal sound:
C6/9: X(3)2233
So if you are playing quartal chords, they can pop up for that reason, but really, in that case, going for quartal sounds is the primary motive, and a 6/9 chord may just happen to fit.Last edited by BigDaddyLoveHandles; 06-09-2010 at 06:56 PM.

I live with maj6/9 chords, I rarely use maj7ths or dom 7th chords, ex. I VI II V, I usually play, Key of C, starting ... wait I'll make quick PDF file...

The last chord in 1st ex. is G7b13

that m3 (#9) with the natural 9 on top--the D9sus--is really pretty. i wouldn't have thought of it.

I have not much idea why cycling a 6/9 in seconds works, except it's a kind of whole tone thing, but it does, usually, or seems to.)

As the fellas mention, it is an alternative to a maj7 chord, and is just another tool for the toolbox, or different color for the palette. As jazz players, we need as many of these sorts of things as we can so we can offer our audience different sounds. Good luck

Don't end a beatles tune without one!
They can actually be a little less dissonant than a maj7 at times...If you put that 7th and root in the same octave, a good ol maj7th can sound pretty hip. I think of the 6 and 6/9 as very consonant sounds...

x3x453 CMaj7
^^^ ???? Meh
Maybe in a modal tune...
ALSO: Min6/9 chords sound very gypsy jazz to me (6th, in general, I guess...)

The good thing about 6/9 chords... they are as fun to say as they are to play!
-
I play a lot of Brazilian music - hardly a tune without 6/9's all over the place.
-
Even Metheny uses the 6/9 chord. For example in 'Bright Size Life' the BbMaj7 chord in the A-section (Not to be altered with the BbMaj7b5/A) sounds, at least to me, like a Bb6/9 and not a Maj7-chord.
The 6/9-chord is also good for scale substitutions between the major scale and the lydian scale.
-
I'm teaching "normal music" (I mean music with the diatonic, pentatonic and blues scales) on line to a guy and I'm teaching him to be able to construct chords of all kinds by himself. He only played major and minor chords with some 7th around there, but I believe in the variety of chords. He already has learnt all the notes on the fretboard and where the intervals are on all strings when you have the root on whichever the string. Soon he'll enjoy the 6/9 chords too.
-
the major 6/9 pent scale 12356 produces some very nice 3note chords that can enhance solo lines with harmonic support and break the anticipated single line for the listener...nice effects....also the minor 6/9 and the minor b6/9 pent scales and the chords formed from them are good to explore
play well
