How can we memory the following secret code effectively？

The string of secret code：

TWINKLETWINKLELITTLESTAR

The first way ～ (use chunks of 24 alphabets to memory)

If we only know alphabet ,we may memory it word by word.

T,W,I,N,K,L,E,T,W,I,N,K,L,E,L,I,T,T,L,E,S,T,A,R

The second way ～(use chunks of 4 words to memory)

If we only know word and don’t understand the meaning,we may find four words and memory them .

“TWINKLE” 、” TWINKLE”、” LITTLE”、” STAR” 

The third way ～(use chunk of a sentence to memory)

If we only know sentence and don’t know the song,we may memory a sentence .

” TWINKLE TWINKLE LITTLE STAR”                   

 (Because we understand the meaning)

The fourth way ～(use a small part of the super chunks to memory)

If we know completely this kids song “Little Star”, we may memory it with the rhythm of the song.

 ∼ TWINKLE ∼  TWINKLE ∼  LITTLE  STAR    ∼

                               (song with melody)

 (Because we already know the code is the first sentence from “Little Star”song)

So the method of effective memory depends on the rich degrees of our memory chunks.

Incorporating the more of our mental, physical and emotional layers, the easier we are to memory and extract it.
