Hey LGM Fam,
I have a question for whoever can help. I am trying to incorporate extended chords into my playing and I am not sure how or when to integrate a 9th, 11th or 13th chord to get that full sound. For example, can I play a C13, C11, or C9 in place of a cmajor to get a different flavor or should I play something else. I probably can learn more through trial and error but I am confused and not sure that will accomplish much. Please shed some light on this subject. Are there certain extended chords that are used instead of basic chords on a regular basis, or does this just come with practice? If you could help, please let Jesus lead you to do so.

Hey Qwan,
Though it is theoretically possible to add most extensions to any 7th chord, there are certain general principles that can help. It is a good place to start.
The general rule is. In general, avoiid tritones between an upper extension and any other note of the chord (except in dominant 7 chords) since the tritone gives the sense that it is a dominant chord and will have a tendency to confuse the function.
Major 7 chords -- Extensions 9, #11, and 13 are available. Ok for some reason the tritone created by 1 and #11(#4) works in this case. It is the 4th of the Lydian mode. The natural 11 is a tritone with the 7th and you have the same notes as the dominant 7th built on the 5th of the chord (CMaj7 11 == G11) The dominant feeling tries to take over. b9 and #9 cause similar problems.
Added 6 chord -- Extension 9
Minor 7 chords -- Extensions 9, 11 (#9 == m3 of main chord)
m7b5 (half diminished) and dim7 can take a 9 in some instances. Since these are often used as dominant 9 and dominant b9 with out the root, extensions are difficult.
Dominant 7 -- Extensions b9, 9, #9, 11, #11, (b13), 13, as well as suspended 4, b5, and #5. These extensions can be used in various combinations. Some chord voicings work better than others. E.g. A dominant 11 will often avoid the 3rd of the base chord, though some voicings can work.
Along with extensions comes the issue of "Chord Voicing" which is chosing the particular notes and the arrangement of those notes for the type of sound desired. To play all the notes of extended chords is not always desirable. "Voicing" requires a little bit of experimentation, but here are some ideas to help:
1. Avoid the root in extensions above the 7th (or added 6). The root is taken up by the bass player, bass pedals, or L.H. either as L.H. Bass R.H. Comping or chord + melody, or L.H. picking up the bass followed by it playing a chord voicing.
2. Pick the notes necessary to define the chord. The third is required (except in instances with 11 or sus 4). The 7th (or added 6) is required - particular in dominant 7ths - to define whether the chord is dominant or not. The highest extension is required for that sound. Any extensions in between, unless altered, are implied.
Here are come examples
Cmaj chord -- CM7 or C+6 (root is left of slash, voicing is right)
C/ E G A D = C 6/9 - 3 5 6 9(G is added to fill it out to four voices)
C/ E G B D = C Maj 7 - 3 5 7 9
G7 chord
G/ F A B E = G7 9/13 - 7 9 3 13 (Sometimes the 3 is left out here) -- The 9 can be flatted to make G7 b9/13.
If you need an 11 or sus4, simply raise the 3 (7 9 11 13)
G/ B F A# = G7 #9 - 3 7 #9 -- This voicing gives the feeling of the B nat against the Bb(A#)
Dm7 chord
D/ F A C E = Dm9 - 3 5 7 9 -- for Dm11, you could shift the 5 down one step or do the following
D/ G A C F = Dm11 - 11 5 7 3
Being rootless voicings allows the player to do some things with the roots. Some voicings work with the tritone substitute root. Some (like doing Dm9 G11) simply change the root with the same voicing (D then G bass with F A C E)
Or C/ E G A D = C 6/9 Change root to F
F/ E G A D = F Maj 7 9/13
You can also move the notes around in the voicing (G A D E or A D G E)
This only touches the tip of the iceberg, but I hope it gives you some ideas.
