Behold: total evasion of the simple question. I’ll repeat it: If one persons earworm of the first notes represents all the chords, and the person can even pick out the different instruments, and another only remembers 4 simple tones and the rhythm, what is the meme?
If you are saying that they are two different memes, then the opening 4notes of Beethoven’s symphony IS NOT A MEME. It is at best, a bunch of memes. bang goes your primary example of what a meme is as a unit, thank you very much.
g’night.
