Well, even your first musical example has no (initial) KeySignature ;)
>>> melody = \relative c'' {
>>> \time 4/4
>>> c1 \key d \major d \key e \major e \key f \major f
>>> }
For the arbitrary reuse of a variable, this variable needs to be
defined at toplevel.
It's possible to update such a toplevel-variable by using an engraver,
though if you clear that variable in the engraver the value(s)/entries
are only available _in_ the score where the engraver works.
For multiple scores in the same file this means: if you don't clear it
then the values will accumulate (or override themselves).
Additionally the engraver updates it too late to have direct access to
the new values for other toplevel-markups.
So I decided to let the key-sig-names accumulate in a toplevel-list,
numbering them. Also, I wrote a markup-command where you need to
select the correct entry by using a number. A markup-command is
processed late enough.
Code attached, note the comments.

Re: Key Signature name in Markup
Hi Harm,
I hadn't really thought about no key signature as being an issue, but I can
certainly see how it can cause confusion.
I think you are correct in suggesting "no key signature present" would be
the appropriate output, although I'll admit I'm unlikely to ever come across
such a case in my use of lilypond.

Hi,
thanks for clarification.
I thought a bit about it and I think it might be possible to store the
initial key-signature-name and let TextScript get this name under
certain conditions.
Though, what to do if _no_ KeySignature is present?
Could be c-major or a-minor or e-phrygian or maybe nothing of it but
rather dodecaphonism or ...
How to decide?
Best would be to output something like "no KeySignature present", imho.
What do you think?
Cheers,
Harm

The snippet works insofar as it gives me the name of each key signature,
which is very close to what I want. However, I'm only interested in storing
the name of the first key in the piece in a variable to use in text later,
rather than displaying the name of each key when the key signature changes.
I can deduce that the last three lines of the snippet (below) are
responsible for printing the name of the key signature above the stave at
each key change.
(ly:grob-set-property! grob 'stencil
(ly:stencil-combine-at-edge key-sig-stencil 1 1
key-name-scaled padd))
What I would like to do is change this somehow to set a variable to the "key
signature name".
I suspect what I need to do is remove the three lines above and replace them
with some sort of command that first tests whether the "key signature name"
variable been set; if yes then do nothing (to prevent overriding the
variable), else set the "key signature name" variable to the name of the key
signature.
At some later point in markup, I'd like to be able to reference the "key
signature variable", e.g.
melody = \relative c'' {
\time 4/4
c1 \key d \major d \key e \major e \key f \major f
}
\score {
\new Staff { \melody }
}
\markup { Some text later that states that the first key in the piece is in
*\key_signature_name* }
and have the text say "Some text later that states that the first key in the
piece is in *C major*".

Key Signature name in Markup
Hi, Just wondering if the following is possible or not, and am happy to be told it's way too complex and not to bother. Is it possible to extract the name of the first key signature in a piece (single staff) after adjusting for any transposition to use in text markup? (e.g. looking to get the phrase "C major" if there is no key signature before the first note (i.e. default key)). I have come across http://lsr.di.unimi.it/LSR/Item?id=856, but have no idea where to even begin modifying it (some of the changes are obvious - I can tell I don't need the rescaling bits, but I don't know enough scheme/lilypond internals to work out how to change it to give me just text). If anyone has some pointers, they'd be much appreciated. If I'm trying to do something a bit too foolish, let me know and I'll give up on that.
