Extended arpeggio help

I understand that in a C major arpeggio, the notes are C, E, and G, Root, 3rd, and 5th. And by adding the B, we get the major 7th, or a A#/Bb to get a dominant 7th arpeggio. But what confuses me is when we start adding extended bits. I know a 9th is a 2nd an octave higher, so are we playing C,E,G,B,D , or are we playing C,D,E,G,B? I also am asking what note it means by an octave higher, does that mean an octave higher than the 2nd after the root we start the bar on (IF we start on the root)?

It also seems if we get to completely extending it (9th,11th,13th) are we just playing a diatonic scale now?

Tensions go at the top of the voicing in root position, so C E G B D. The thing to remember is that not all chords get all tensions. You're not going to see a major 7th chord with b9#9b13...

Here's a nice chart

Don't refer "A#" as the Minor Seventh. From the root of C, "A" is the sixth scale step. C7 = C, E, G, Bb.

Simply stack the chord tones in Thirds, deriving the notes from the Scale that chord is from.

In the key of C Major, starting on the first scale step of "C", the chord tones stacked in thirds are: C, E, G, B, D, E, F, A. You'll notice that ALL the notes from the C Major Scale are used - this is called "Harmonizing the Scale".

Do this with the second scale step of "D", the chord tones stacked in thirds are: D, F, A, C, E, G, B. All the notes of the C Major Scale are once again used.

You can do this with each scale step.

Usually, NOT all the extensions are used. For instance, a Cma13 would would use C, E, G, B, D, A - but not F.

You can use ANY Scale or Mode to do this "Harmonizing the Scale" exercise.

For example, using a G Harmonic Minor Scale - G, A, Bb, C, D, Eb, F#, G - build a chord off "D": D, F#, A, C, Eb, G, Bb. Drop the "G", since it conflicts with the F#, and you have a D7b9b13. One can even get away with using ONLY D, F#, C, Bb and still realize this chord.

As Ed points out, you do not need to pile on every extension. But knowing the extensions will help you find notes to improvise with or build bass lines.

I'm not following this.

This is what Harmonizing a Scale does.
