Well, I just thought of this, but if you consider three features of language, discreteness, semanticity (linguistic units map to other 'real world' objects), and arbitrariness, you can draw an analogy between language and Analog-to-Digital/Digital-to-Analog Converters. I won't ramble on about everything that falls out of that analogy, but a lot of stuff does!
I did a little test-run with a few songs and noticed that I don't really remember the music -- I remember the lyrics -- and I remember them in stanzas, with the intervening music not really stored -- (so) I recalled some stanzas out of order -- and I seem to rely heavily on the pitch information, intonational melody, and such that is stored in the lyrics in order to recall and reconstruct the music. There's also a definite difference between recalling lyrics to music and recalling literary works like poetry and plays. For example, I can recall Shakespeare faster than I can speak it -- and with very little effort -- but it's almost like I need to build the whole song in order to recall just the lyrics. (I'm just learning an audio editing program, and I think this is how they store files -- instead of storing the original song and rewriting each change, they store only the changes that you make, which are kind of layed over top of the originial and need it in order to play -- and note how much easier you can recall a song that you are listening to at that moment. Anywho.)
This doesn't surprise me because I'm a language person and don't know enough music notation and terminology to have built an efficient ADC, if you will. But I wonder what information someone like ST, who 'speaks music fluently', has stored and in what form. Does he remember, e.g., the actual notes (i.e., he recalls auditory signals and hears them 'in his head') or linguistic information like the letters that are assigned to the notes (which he can then convert to sound signals).
Oh, and if you add in a writing system, you can switch to the visual channel, so you're not stuck with temporal ordering and can make better use of matrices and such. Anywho, did I say I wasn't going to ramble? Woops.
