Retrogression

A retrogression is just a backwards chord progression right?

is when a celestial body moves in a direction contrary to another.

Retrogression: A harmonic motion in which each chord moves to a new chord more distant from the tonic as measured in ascending-5 th root movements, such as a supertonic to a submediant.

Is your google broken?

Example please?

super tonic vs leading tone?

Example please?

Although the description is not perfectly and theoretically correct, one could say that the dominant goes to a chord that is not the tonic and that has no or minimum tones in common with that same dominant. This tends to create forbidden parallels. The term itself is not very useful anymore, because as soon as you start thinking in seventh, ninth, eleventh chords, etc., then any chord has an (en)harmonic relative somewhere (tritonus relationships and bII dominant 7th substitution for the real dominant 7th chord in the scale, for example). More important is to create a good base line. The rest solves itself.

Are you asking me to do your homework?

It's when the chord progression doesn't progress any more.  It regressed.

I IV V I   <-- Progresses
I V IV  <-- Regresses     The horror!  the horror!   

Going through the circle of 5ths can give you the feeling of progression.  Then you hear something that regresses and it sounds off.

There are passing and neighbor chords too.  You could have....  I IV V IV V I... (I think) and the middle IV is just a neighbor chord, not really affecting the progress.  You could simplify it out.

I don't remember it that elaborate in my theory classes.  That's just going down by diatonic fifths though.

I had heard of...
I   <---  V     <-- IV or ii  <--- everything else  (I think.  I'm blanking on this.)


Haven't heard of the word elision being used much, except for phrases.

ii and IV are pretty much the same chord in terms of function.  Same with I and vi.  I think iii is in the 'everything else' category.  If you're wandering around in 'everything else' who knows what key you're really in over there.

I wouldn't worry about categories.  I haven't seen that used much, unless it's theory class.

It's all just  I IV V I     or   I ii V I.    All I V I.  Or all I.  Everything's just Do if you keep simplifying it.     A lot of progressions are just some kind of variation on I IV V I.  If it's not moving forward like that, then it's a regression, something to avoid in classical music, like parallel fifths.
