With the help of SCALER, I now learn a lot of common chord progressions under major and minor.
But in other modes, I don’t understand.
Such as Locrian mode Chord progression.
Where did this knowledge come from?
Can anyone tell me a few Locrian mode Chord progression?
It arises from the harmonisation of triads on a diatonic major scale on the 7th degree.
It’s not exactly a scale that you would want to listen to for too long. You can read the basics in Wikipedia
If you are a guitarist there is a reasonable introduction at
You can also see Danny explaining a locrian sequence at
and a backing track at
which shows the chords of such a progression.
Why?
It can easily fix your sleeplessness issues
or give you nightmares, if you do fall a sleep 
Or, equally effectively, I could listen to rap, D+B, or (heaven forbid ) folk. 
You missed the trap
While the TRAPpist is bombastic if you like those “vibes”
I like this scale. Cool progressions.
Yes, I can say it sounds well with many instruments and styles
