Thanks, this is much more useful.

First, are you aware of the \relative and \transpose commands?  They
would make this much easier to write and read.

Second, I highly recommend that you only write one bar (or so) per 
line.  Maybe
two bars or phrases.  Yes, it means that you can't see so much of your 
file on
the screen at once, but trust me, it's worth it.  I used to pack 
together a lot
of stuff on each line, but when I go back and try to fix files from 
three or four
years ago, it's quite difficult.

Let's look at what you have.  I'm going to ignore octaves, and space the
notes into eighth notes.
{
fis32 r a a       r16 r32 fis        fis32 r2 r4     <-  here things 
get tricky.  Why do
you have a half note rest here?
Should that "r16" be "r32" ?  Or should you only have one fis ?  Or are 
you
missing some 64s ?


aha... apparently Completion_heads_engraver doesn't work on rests.  This
might be a bug, or it could be a mistake in the docs (ie saying that it 
doesn't
work on rests).  I'm looking into it.


Try spacing out the rest of the input into eighth notes.  I think 
you'll find
some suspicious things in your code.
