A way to derive the Dorian musical key

If we make the usual expansion 1  3  5  7  9  11  13 from bass A:


A C E G B D F (for example playing sustaining notes on the piano).
F does not sound right while #F does.
So we have:
A B C D E #F G A ie A Dorian


Similarly with bass D:
D F A C E G B D sounds superb
D Dorian is:
D E F G A B C D ie
re mi fa sol la si do re
All white or natural keys.


The Dorian key is very important as it is minor but the chord created with bass the 4th note of the scale is major 3rd instead of minor third. Therfore this chord sounds happy and uplifting:


It can be heard:


At the sung vocalise part of the Great Gig in the Sky - Pink Floyd, Claire Torry
The chord progression is G minor 3rd minor 7th to C major 3rd major 7th major 9th
