You can forego the above two lines (of course removing the respective
closing parens later on) nowadays.
(make-music 'NoteEvent

Ok, make-list is a tad-bit more basic and efficient than the iota I
employed.
I get a GUILE error on line 5
$(let
I don't. Copy and paste error?
$@(let
but that didn't work either (obviously I don't know what I'm doing .
.)
Obviously. $ splices a single expression (which is what
make-sequential-music produces) into LilyPond, $@ splices a list of
expressions.
I recopied and pasted the whole snippet - which gives the same result as
right-click and save.
The original has:
#(let . .

but I get a GUILE error on that too . .
Thanks,
Phil.
