music flow, i do not get it...

what is the meanig of music flow. i have watched the video 3 times but my brain just is stuck there. i got along very well with all the other subjects so far.

why should i learn them, and how? is ther a music flow for every single chord?
it says

I "X" V I

okay I is the starting chord, and then the V i see too, its the 5.th up, and then back to I.

but what is this "X"? does it mean its a variable like in maths?
and then andrew says that is IV but it can also be II7?
I understand what IV an ii7 is alright, but what is the meaning of it? why do i have to put something there?
why not just I V I ?
i just don't get it. can it be a iii as well? or a IV? or a VI?

can anybody name an example of a song where the flow is in?
is this not more importent for composing rather than playing?

The flow? I dont know what video of Andrew you're talking about, but I assume you watch one explaining chord progression.

Each scale has a set of notes, lets stick to c major scale:

1 2 3 4 5 6 7
C D E F G A B

1. tonic
2. supertonic
3. mediant
4. subdominant
5. dominant
6. submediant
7. leading tone

Instead of numbers in chords we use V ii I etc. ( these old weird "numbers" ). When it says I - ii - V you should play the first ( cmaj chord ), then second ( dminor chord ) and at last the fifth ( gmaj chord ). I dont remember the difference between the i and I tho. I skipped this theory, so I need to get back to it when I got time to learn it properly.

Anyone wiser, correct me if i'm completely wrong

Yes, a variable, just like math. If I remember correctly Andrew gives a couple of examples of what could be in the variable X.

why not just I V I ?

It could be. Like math, the variable could be "0" for this case.

Speaking of math, I would say there is an inversely proportional relationship between math and music. For instance, the more difficult and complex the piece of music, the more one is drawn into the sound and enjoys it. Where with math, the more difficult and complex the problem, the more one wants to quit the university or change professions.

This means X equals whatever you want it to be? You put whatever chord, ii, iii, Vii or other inside X, and you get a chord progression of 4 chords.

That's what Andrew said in the video, you can use pretty much anything there (for X) and just gave a couple of popular examples.

Weird numbers mean, roman numbers

yeah, thanx. but why should i use music flow? is it just another "trick" to get good-sounding music?

i know roman numbers, that is not the point and that they refer to the notes in a scale is clear to me.
the difference with big I and i is also logical. in capitive (big letters) are the dominant notes and small letters are the weak ones.

You have a link to the video?

Maybe get a book about harmony if you want to know a lot of details... it's quite a big subject I think...
