I could not find Carol's video you speak of, however, extended triads - dirt simple explanation.
To build any chord you start with a scale and stack every other note to build that chord. Called "stacking 3rds". C
B C D E F G A B
For a Triad we would use the C E G notes.
For an extended chord we would add more notes to our stack. C E G B and this is not called a triad as there are more than three notes in the stack. So what do we call it? As B is the 7th note in the C scale the C E G B stack is called the 7th chord.
Add another note and you get the 9th, another gets the 11th, and one more gets us to the 13th.
I'll have problems playing all those notes - a C13 has these notes (C E G B D F A) I don't have enough fingers to pull that off. So I can do one of several other things, one is to leave out some of the notes. The following chart will help. http://www.smithfowler.org/music/Chord_Formulas.htm
The notes in () are optional, can be left out. Or another way
you could make slash chords
and you play the slash and the solo instruments play the other notes.
Why would you want to do this? DLowRider hit it on the head -- you can get some really beautiful sounds doing this. But, you alone do not have enough fingers to pull it off so you need help. Solution; you take part of the chord and let other instruments take the notes you can not "finger". Together we'll make those beautiful sounds.
Now go back and read the posts that speak of breaking the chord down into something else - same notes, but in a different order - which can make a different chord all together. Took me a long time to realize what they were doing, and why.
You take that, I'll do this and together we end up with what we need. The songwriter or composer normally will take all that into consideration when writing the score. We play the bass clef or the slash, whichever..... the other notes necessary are put into and played by the treble clef people.
