Hi List,
I need to get an ancient tab with a standard markup alignment instead of
the default vertical one.
Unfortunately, this code has no effect:
\version "2.18.2"
#(define-public
(my-fret-letter-tablature-format context string-number fret-number)
(let ((labels (ly:context-property context 'fretLabels)))
;; changed from make-vcenter-markup
;; has no effect:
(make-simple-markup
(cond
((= 0 (length labels))
(string (integer->char (+ fret-number (char->integer #\a)))))
((and (<= 0 fret-number) (< fret-number (length labels)))
(list-ref labels fret-number))
(else
(ly:warning "No label for fret ~a (on string ~a); only ~a fret labels
provided"
fret-number string-number (length labels))
".")))))
[...]
Any idea?
I'll create a patch making this less hard-wired. I'm not sure about
what our default should be, however.
I checked some lute tablature I had here as part of a partitura in order
to see what alignment is appropriate. Good grief. In the lute tab, the
letters were not crossing the staff lines but were _above_ them.
Alignment was definitely _centered_ vertically rather than on a
baseline. Except for the letters on the top line: those were either
baseline-adjusted, or bottom-aligned (hard to say but probably the
latter). Good grief. I certainly hope that this tab (1953) was not
representative.
I don’t have much experience with tabs, but can reference some historic
prints:
London 1613

Rome 1616

Breitkopf 1760

In case it be of help.
Yours, Simon
