You can make this simple or complicated. In reality it is very simple.
Progression:
A progression has been shown, with years of analysis, to most like
consist of a movement away from the Tonic note and then PROGRESSING
back to tonic. The route taken has shown to be following the cycle of
5ths back to tonic. So if you move from Tonic, C for example, to say a
vi chord or Am. The typical progression would be I vi ii V I
starting with the vi, each chord root resolves down the interval of a
5th until it reaches tonic or C in this case. Question: But the IV
is not in that progression so how can that be? Answer: Good
observation. In the never ending search for variety and other
characteristics of various chord colors and to accommodate bass lines
and for lots of reasons, there can be substitutions. Historically the
cadence in CPP would most likely be I vi IV V I. If you look closely,
the ii chord is spelled D F A and the IV chord is spelled F A C. They
share two notes out of three. The ii is often in its 4 note spelling D
F A C which contains the entire IV chord. The CPP also liked the base
line of 4 5 1 as a strong cadence. The approach of the F to the G in
the bass is heard as emphasizing the V and they more commonly used
this for a cadence. It still fits into the scheme of the progression
of 5ths toward the tonic for that reason. In Jazz you are more likely
to hear the ii7 V I than the IV V I but they both follow the same
progression rules based on the 5th and they both serve as a final
cadence or a tem****ary cadence.
Thus retrogression is simply the reverse of this process.
Retrogression would basically follow the I V ii vi iii or variations
of these root movements.
If you like more step by step instruction, either find an old theory
book or probably someone here will give you the various rules for
progression. In either case, the end result will be that they will
follow the basic rule of descending 5ths back to tonic with various
adjustments as considered best by the composer.
Does this help?
