Now that I think about it, you do not have to use make-pitch. You can
extract the pitch information from a note, like this:
%%% BEGIN %%%
\version "2.10.0"
#(define (getpitch mus)
(ly:music-property
(car (ly:music-property
(car (ly:music-property mus 'elements))
'elements))
'pitch))
myPitchnames = #`(
(myowndeepceses . ,(getpitch #{ ceses, #} ))
(myownf . ,(getpitch #{ f' #}))
)
pitchnames = #(append pitchnames myPitchnames)
#(ly:parser-set-note-names parser pitchnames)
{
c' d' e' f' myowndeepceses2 g'4 a' myownf1
}
%%% END %%%

Yes, you can't simply write
\noteone4
to get ees'4 when \noteone is set to {ees'}
this has bitten me as well, and it is caused by the fact that \noteone is not
just some string, but a fully-fledged music expression.
I have no simple solution. I think it would involve writing a small scheme
function to take a music expr and replaces it's duration.
You could maybe look at

I don't understand what you are using it for.
Why will you put a single notename into a variable?
Could you elaborate a bit more on your project?

Newbie question about variable durations
I thought I had this figured out, but now I'm stuck. My program generates midi
notes and converts them to lily variables (ie noteone = {ees'} ). What I need to
do next is add my durations onto them. It seems so simple but I get error after
error.
What do I need to do to combine the strings together so it can be read as
"ees'4" from \noteone and 4?
