Hello fellow Lilypond fans,

since the Renaissance Alla breve mensura is usually rendered in modern
notation as 4/2 time, I'd appreciate the introduction of a genuine
possibility to display this time signature as slashed c (exactly like 2/2
time). In my opinion, the easiest solution, and well acceptable for me,
were to make this standard behaviour and turn it off by
\numericTimeSignature. However, it would be equally possible to add
another selectable value for the #'style property of TimeSignature.

All the reference works I can find (Grove, Oxford muxic, Gardner Read) refer to alla breve as 2/2. Please can we see evidence for it being employed as 4/2?

If the default time signature style is going to be augmented, I'd like to tack on a request for ¢¢ and cc to be put where they belong, wherever that is. _Maybe_ ¢¢ is 2/1 and cc is 4/2 (which is why I'm mentioning it here rather than in a new ticket).

There is a discussion in this thread.

Simon cited this example of ¢¢ in a piece by Schubert:

e.g. the second Kyrie and Gratias from Bach's B minor mass are both such (4/2 denoted by cut C).
Of course, renaissance music has no notion of barring, so rendering an original alla breve piece in 2/2 or 4/2 is purely editorial.

If the time signature of those Bach pieces is denoted by cut C, why say "4/2 denoted by cut C" rather than "2/1 denoted by cut C"? (I'm not disputing but asking for clarification.)

I found it interesting that there is variation between editions:

Issue 3286: add single-C time signature style

This style is identical to single-digit except that C is printed
instead of 4 and cut-C is printed instead of 2.

Passes make, make check and a full make doc - but there have been some comments on Rietveld in between when the patch was issued and when it was tested. I'm going to leave it on review for now as I'll check again anyway when the next Patch Countdown occurs (tomorrow).

Here's the patch. Is is appropriate for me to create a new ticket to update documentation?

Issue 4186 removed the feature that was added for issue 3286. Issue 4204 was a better solution.
