Are there rules for the order in which chords are played in a given key?please help

i'm wondering if there are rules for the order in which chords are played in a given key.For example,is a vi I vi I progression ok?such as in the key of B which would be changing between the chords G#m and B.This is just an example.
I guess what i'm asking is,is it ok to play chords in what ever order i want as long as the chords belong to the same key?Or are there chord progression rules against this?

If it sounds good, man, play it...... I'm not one to worry about progression, I recommend just making it up as you go along and if it sounds nice, you've got to be doing something right.

There are no rules, but there is an undefined set of common chord progressions and orders that sound good, and are played commonly.

For example the V going to the I, what we call the full cadence, or the II V I progression etc

thanx for replying

Not "rules" per se, because you can play any series of notes or chords that you may desire. But there is system in tonal music called Functional Harmony.

I did an in depth post on it here:

Imagine if there were rules that were so strict that a progression would not work unless the strict guidelines were followed precisely///////////.....
If this were the case, by now every possible progression would probably been used to death.
Although guidelines do bring Tonal Function to a progression, how the Tonal function is processed opens the door to many opportunities.
Example; The Key of B can function differently depending on how the progression leads. The Key is shared with G#m, so the progression could function in the Key of G#m.
Another option is that the progression could function in the C# Dorian Mode.
The options go on and on.

A progression can also temporarily drift in and out of key to create some dissonance with the desired chord(s) and return with a cadence strongly outlining the Key.

A progression can modulate to another key (and back again, if desired), by introducing a Secondary Dominant for example and give the song a whole new Tonal Centre, if desired.

Etc.,...etc,....etc,......

I would say that the main rule applies to knowledge in Theory (so that possible options don't go undiscovered) and using your inner ear to hear how the options function with each other.

thanx for the link cschlegel.I now have a better understanding of what music theory is about.You guys have helped.thanx to everyone who responded

ditto that

yeah, music can be anything you want it to be, you can just scramble random notes together and call it music, like those painters who splat paint all over and sell it for millions...

...and yeah, you can play any chord in any order in any key if you want, as long as it sounds good to you.

you can play ANY chord in ANY order with ANY timing ANYWHERE you want, i dont see why people dont get this....music is art.
