The map returns a list which means that the 'elements of the

list.
Try the following and have a look at the output produced by
\displayMusic:
%%%%%%%%%%%%%%%%%%%%
\version "2.19.82"
voiceA = { e' f' g' }
voiceB = { c' d' e' }
%this works
\displayMusic <<
$(eval-string "voiceA")
$(eval-string "voiceB")
%this works too
$(make-music
'SimultaneousMusic
'elements
(map eval-string '("voiceA" "voiceB")))
%%%%%%%%%%%%%%%%%%%%
%%%%
$@(map eval-string '("voiceA" "voiceB"))
%%%%
That should work too, I think.
