The Saddest Minor Musical Scale

[Different]

Don't forget that if you only consider the 7 basic triads of these scales, you still have 3 major chords, 3 minor chords and 1 diminished chord, no matter if you're in the major realm, or its relative minor scale.

As you mentionned in your first post, chord progressions do matter a lot. Even if you're in, let's say, C Major, you can still use pretty sad/depressing progressions like I-ii-iii-vi.

Frequencies are also a weird thing. Play a D Minor scale starting on D3, then play it from D1 or D6 on a piano. Not exactly the same experience

All in all though I'm not saying natural minor isn't a sad scale, I'm simply giving more context ^^

That's a good observation of looking at chord progressions. I'm still learning more about chord progressions, but I can see where you're coming from. Funny thing is, I just learned the basics of chord progressions from last year :p

D3 is a good place to start for the D Minor scale, and so is D2. D1 would be too lifeless and D6 would be too happy in a higher octave. So yeah back to your point, it does depend on the experience/frequencies.

In general, I feel that categorizing or comparing scales, regardless of their respective modes, does a disservice to the individual relationship everyone has with music.

Well, in general I can understand how it might be a little misinterpreted, depending on how you look at it. Also, it depends on who the targeted audience is when considering that relationship with music. I think once you break down the scale comparison terminology, and consider certain genres that go by that scale (once heard by the listener), it becomes a different story.
