Dispensable Fifth

[rocketpost1]

In extended chords why is the fifth interval so dispensable ?. On the guitar, if you play C9 on the inner strings starting at C on the A string, you have intervals of 1 3 b7 9. You can of course add the fifth (G) on both E strings at fret 3 but this chord sounds so good without the fifth. I know jazzers often use the fifth as a bass note and forget about the root which is usually covered by the bass guitarist.

I didn't expect zero answers which indicates that this is probably the wrong forum for a serious question. The answer bank seems to be for mainly jokey and trivial questions.
I did answer my own question by searching elsewhere which is what I should have done anyway.

The forum is fine. The issue is having the patience to wait for someone knowledgeable in musical chords to see the thread and express an opinion or knowledge.

Great comment Tils but what on earth does it mean ?.

The problem is that on A Sunday the crossword clues flood in so posts disappear off Latest posts within a minute. After that, unless someone happens to dip into one of the now 'minor' categories - in this case Music teh question is unlikely to be seen.
Before teh revamp all the categories were always visible on the left and I'm sure I wasn't the only one who regularly dipped into check sections of interest such as Music, B&F etc, but now do it less often as we have to ' go round the houses'
