Help with chord progression?

Actually, all of your chords do fit perfectly with chord theory. The triads/chords in a major scale go 1-2m-3m-4-5-6m-7dim-8

In the key of Eb, those chords would be

1 = Eb

2m = Fm

3m = Gm

4 = Ab

5 = Bb

6m = Cm

7dim = Ddim

The fact that some of the minors are minor7 still fits. Here, look at this: http://www.guitar-chords.org.uk/chords-key-e-flat.... This is a guitar site, but the chord theory also applies to piano.

As for a progression, all the chords listed above are your palette and you're the artist. You can arrange the chords any way that sounds good to you and call it a progression.

even as writing and recording, we talk of 'the riffs' as in each and each and every seperate area defined by technique of a distinct progression in notes/chords/blend or a replace (of riff), so 2d riff, third riff, repeat first riff etc.....its in basic terms semantics i reckon. C A F G, repeated two times or 4 circumstances, thats a riff, then you definitely then replace to taking area in some thing else, and thats the 2d riff, etc. WHY not call them LICKS heheheheeeee ;) even as writing, you would possibly want to bypass anyplace your palms take you on the fretboard....beware of blunders - they can many times be the most blindingly dazzling riffs ever.

There are no strict rules; almost anything goes in contemporary music.

Chord progressions are what other people established a sounding nice. But it can be whatever you think sounds nice. If anyone criticizes you for not following a rule they are ignorant. Just have fun with it
