“Like learning to ride a bicycle” should be the standard for a well structured learnable skill. So many skills we work so hard to acquire are *not* like that.
All symbol-mediated ones and most powered subsymbolic ones (like driving) are not LLTRAB.

It makes you think if it’s all the symbol-mediated the ones that are gumming up the works

Partly, because they introduce a level of arbitrary representation. But subsymbolic can gum up works too. Car driving skill atrophied, unlike bicycle, because the speeds are way out of range for our natural motor/reaction skills.

Muscle memory is a thing for musicians. You forget by which processes you learned some stuff and vice versa. At the sub-symbolic level as there’s definitely atrophy with respect of prosody, meter, rhythm
