In digging through some DiCaprio materials (stashed who knows when from
who knows where) I was surprised to find what's called Herigone's
mnemonic system was used for memorizing progressions. This is usually
encountered via the popular book by Harry Lorayne and Jerry Lucas, "The
Memory Book", published in the late 60's and still in print after 40+
years.
I read that book when I was 17, and though it really only provided me
with the numbers-to-words (and vice versa) routine, I found it
incredibly helpful and always have, though never with chord
progressions.

I did use it musically for awhile when I had a very dull straight job
driving a school bus one summer: I named an object or phrse and then
would convert it to numbers. For instance: "convert them to numbers" is
728411123940 (if memory serves!). Then I'd try to sing that figure.
I still use it when someone tells me a phone number and I have no way
to write it down. If I get just a moment of silence I break it out into
consonants, then to images, and I can at least hold it for a day or
three.
I note also on wiki that a similar memory system, the method of loci
from Ancient Roman and Greek treatises and commonly called the journey
system, "was taught to schoolchildren for centuries, at least until
1584, "when Puritan reformers declared it unholy for encouraging
bizarre and irreverent images."
Thank you, Jesus!
