Hey Ken,
This list is a pretty ingenious way of learning the main sounds of the major system by associating them with a simple journey that takes advantage of our ability to easily imagine and recall spacial information.
The list is a series of places (sometimes called loci) starting above your head and traveling downward in sequence, using your own body as a “memory palace.” Each loci begins with the sound that the Major system associates with the number that it represents. So starting with the Sky above representing 0 and going down through Ball representing 9, you get a place that clues you into each number 0-9…
I’d actually suggest a further addition to this technique by imagining tangible objects or people interacting with each spot that use the rest of the associated sounds for each number, which would give you something like:
0 = Sky: in the Sky you can see ZeuS (0 in Major is represented by the S or Z sounds)
1 = Top of your head: on Top is a ToaD (1 = T or D sounds)
2 = Nose: in the nose is a NuN (2 = N sound)
3 = Mouth: in the mouth is a MiMe (3 = M sound)
4 = Ribs: stuck in my ribs is an oaR (4 = R sound)
5 = in my Liver is a LoLLy pop (5 = L sound)
6 = Joint: in my hip Joint is a guy named JoSH in a rocking CHair (6 is J or SH or CH sounds)
7 = Cap: on my kneeCap is a KeG (7 = K or G sounds)
8 = Fibula; around my Fibula are FiVe golden rings (8 = F or V sounds)
9 = Ball: on the ball of my foot are some PuBes (9 = P or B sounds.)
If you can visualize these places on your own body and picture the corresponding items, you can count down the locations and learn the basic number/sound associations that you’ll need as a foundation to the Major System, which is one of the most powerful memory techniques ever devised.
