all modes are really are playing the right scales with the right chords. if u have a chord that brings out a certain flavour like a major 7th or even better a major 7th sus they have really distinct flavours and sounds. the modal theory comes into play when you know the intervals of the modes not the shapes. then u start to play the write mode for the right chord and targeting the flavour notes. example if the chord progression was from the second chord to the third chord in A major which would be b minor to c# minor. now we have the chords you could just play straight pentatonics the b minor and c# minor pentatonics but that wouldnt bring out the full flavour of what were going for. because knwoing your modes this is a dorian progression the way we make it dorian is we change the chords from b minor and c# minor to having a characteristic from the dorian scale. the dorian scale intervals are 1 maj2nd min3rd 4th 5th flat 6th flat 7th. and the average minor chord has a 1 minor 3rd p5th. now to make this dorian we need to slip in the chord the dorian notes. so what most ppl do is add the flavour note of the minor 7th so u can cahnge the b minor to bminor 7 c# minor to c#minor 7th. what id do is have the bminor chord with a sus2 and flat 7th. and the last chord c# minor 7th. now the chords are arranged u need to start tageting these notes with in the chord a good practice is to record an apperegiated sequence and feel when the notes come about and harmonize some b dorian over the top or a major (be careful always end on the root of b). hope this helps its the same for other scales if u know the intervalic structure (how the scales are made)

correct me if im wrong we all make mistakes

remember music is to be enjoyed not to be confused about.
