About "Em, D, C ,B"

I like this chord progression. Em,D,C,B

However, in minor scale, there is only Bm, not B

This B belongs to harmonic minor, but Em D C does not belong to harmonic minor.

So what minor does “Em D C B” belong to?

Hi @swingmix

You can right click on your pattern in the section C and press “detect”.

This will run a detection and give you a list of scales that can match your progression.
You should find one in the list that contains all the chords.

If you can’t find a scale with all the chords it means that one or many chords in your progressions are simply “borrowed” from another scale. There are lots of nice progressions with borrowed chords.
