So, attached is my first go at that sort of “assembly-required” structure.  
Originally I defined several music variables with “_a”, “_b”, etc. suffixes 
(preserved for alt_music).  However, I recalled from earlier list activity that 
one could also use “.1”, “.2”, etc. in variable names.  Now, as I understanding 
it, if I define music variables main_music.1, main_music.2, etc. then the 
underlying scheme creates a single variable main_music which is a list of 
pairs.  Each pair consists of the number as the first element (car) and the 
musical contents as the second element (cdr).  Now, I can just manually build 
up the whole main melody using { \main_music.1 \main_music.2 … } (as is 
currently done in the attached), but the scheme construction of it as a list 
got me thinking, is there a way to programmatically accomplish this 
concatenation?

Now, I’m almost certain the answer is yes (at least in principle), but before I 
start trying to write a music function that does this, I want to make sure that 
such a function doesn’t already exist.  If it doesn’t, I’d like to know from 
the scheme experts out there if there are any technical reasons why such a 
function hasn’t been written, or if it’s simply a case of no one’s thought of 
trying this before.
