Whats the difference how Classical uses the 9th,11th,13th chords and how Jazz uses the 9th,11th,13th chords?

How does Classical use the 9th,11th,13th chords?

How does Jazz use the 9th,11th,13th chords?

Well, Jazz treats all scale notes equally more or less now, so the notation scheme involving 9th 11th and 13th is just historical here, meaning that along with 3th there is a 2th (9th) 4th (11th) or along 5th or 7th there is also 6th (13th) that belong to ionian (major) or dorian (minor) scale. This part is important because classical masters used eolian scale to resolve minor chords and in opposition, jazz masters used dorian scale (which was used as such till Bach, AFAIK, along with dorian notation of sharps and flats, but i don't know the english name for it).

In classical music you can hardly find a flat 9th in an chord. You won't find any sharp 11th until Debussy (i suppose). Romantism found the added 6th (i mean 13th).

I won't bet my head on it, but it was more or less like i said :)

jazz masters used dorian scale for 9th,11th,13th chords?

AFAIK there is nothing like 9th 11th and 13th chords in jazz, because it is notabene the scale which is leading the harmony and the degrees, not the other way round. So you can make a chord with ALL scale notes with it, but what there really matters is what the scale was.

9th 11th and 13th notes/degrees are these Leading tones?

Why are the 9th 11th and 13th notes/degrees Color tones?

9th 11th and 13th notes/degrees are Tension tones?

9th,11th,13th seems like classical composers just used them

as non-harmonic tones like passing tones, Neighboring tones,Suspensions,Retardations,Anticipation,Appogitura,Escaped tone, Pedal tone or Secondary dominates V9 ,V11 mostly i see in classical

In Jazz they used the 9th,11th,13th as Tension chords,Color chords,Extension chords

How do you think Jazz used 9th,11th,13th chords?

11th and 13th chords are kinda like heavily inverted block chords, so often I see the two used together in many contemporary pieces - I'm actually not too sure which composers started to use 9th, 11th, and 13th chords extensively (I assume it's the impressionists, but maybe there were a few late romantics who liked to use them too).

inverted block chords? what do u mean?

I don't know if that's the correct terminology, but I was trying to refer to the fact that a 11th chord, say d11 (d minor with c major), has the same notes as a diatonic block chord from c to a.

D-F-A-C-E-G -> C-D-E-F-G-A

Voicing the chord i think you mean? the inversions voicing
