Major 11th & 13th

In continuation of where I stopped yesterday
Major 11th (not used as much) and major 13th chords are extensions to 9ths.  

As you look at them, you can see the relationships.  In the key of "C", a major 11th is: C-E-G-B-D-F. A major 13th is C-E-G-B-D-F-A. If you wanted to play all the notes in a major eleventh chord(polychord) You can see that you would need to play a "C" chord and a "B" diminished. Put into numbers, 1-3-5/7-9-11.  
To play a major 13th chord, you would play a C major 7 chord and a D mionor chord. Put into numbers,: 1-3-5-7/9-11-13. 
I wouldn't play all of the notes, though. With both chords, I would leave out the third and the fifth. You have to listen to the chords and drop or use the notes as pleases you.

A minor 11th is formed by combining a 1 minor chord with a major chord on the seventh.  You can see it.

 Note: Key of C, Minor 11th. C-Eb-G-Bb-D-F. For transposing purposes, 1-b3-5-b7-9-11.  Played with both hands; C-Eb-G/Bb-D-F.

To form a minor 13th, you add the 13th. C-Eb-G-Bb-D-F-A.   You can see that this is a minor 7th and a minor chord combined. C-Eb-G-Bb/D-F-A or 1-3-5-b7/9-11-13.

Of all the 11th and thirteenth chords, the one that I use the most is the dominant 13th. They are all, however, good chords to know how to form and use.

I hope that someone finds a chord among the ones posted in this thread that they did not know and that they can really use.
