Hi Valentin,
I didn't have time to follow the SourceForge -> GitLab transition and so I'm
currently trying to keep track.
I didn't even manage to post to nabble using nabble anymore... (???)
If you don't mind, I'll try to insert an one-line change into your merge
request - it' s about the second textual diagram crash I know about:
When switching from graphical to textual representation, tin-whistle will also
abort.
I know that this is rather pointless, as tin whistles don't have any special
keys/holes, not even a thumb hole, but, nevertheless, LilyPond should not crash.
The tin whistle crash can be easily produced by just switching off graphical
representation:
\markup \override #'(graphical . #f) {
\woodwind-diagram
#'tin-whistle % saxophone
#'((cc . ()) (lh . ()) (rh . ()))
}
The cause is in
[...]/scm/display-woodwind-diagrams.scm
(define (generate-tin-whistle-family-entry tin-whistle-name)
[...]
(text-commands
[...]
((stencils
. ,(make-central-column-hole-addresses
CENTRAL-COLUMN-HOLE-H-LIST))
where it should really be CENTRAL-COLUMN-HOLE-LIST (without the additional "-H"
in it)
Anyway, I think it a good idea to work on some historic shortcomings of the
woodwind diagrams.
I don't play woodwind instruments myself, either, but some of my closest
friends play clarinet and saxophone, representing a rather full range of these
instruments. And, thanks to Corona (long story), I happen to currently have
all of these instruments sitting in my living room. 😊
As the original post was about saxophones, I'll stick to the saxophone family
(for the time being).
Instruments at hand:
- Baritone Saxophone
- Tenor Saxophones (several)
- Alto Saxophones (several)
- Soprano Saxophone
No bass saxophone or below, though (sorry), and the sopranino is several
hundred kilometers away, no sopranissimo. No C melody.
As not all of us (and especially people programming all these woodwind
diagrams) play or technically know all of these instruments, I'll just quickly
outline the special sax situation, if you don't mind.
Saxophone fingering
Saxophones are transposing instruments and the layout of keys and thus the
fingering is the independent of the type of saxophone:.
Same written note means same fingering.
That's why the LilyPond woodwind diagrams for soprano, alto and tenor
saxophones just refer to one and the same plain 'saxophone definition.
There's only one exception for the baritone saxophone: Many baritone saxophones
have an additional key to extend the range down to low A (usually, Bb is the
lowest written note on a saxophone).
Yesterday, I just took a side-by-side photograph of a baritone saxophone
(Selmer Super Action 80, with low A key) and an alto (Selmer Mark VI, without
low A key, of course) and marked the low A key (green) or the place where it
would be (red). The black thumb rest can be used for orientation: The low A key
is directly opposite the octave key, both surrounding the left hand thumb rest.
One reason why I attached the photo is that probably not too many people may
ever have seen a low A key.
But the other, more important reason is that I'd prefer to have some suitable
kind of graphical representation of this key (instead of just printing "lowA"
or a circled "lowA" for low-aT.
Perhaps somebody has a nice design idea. Unfortunately, most saxophone
fingering charts (even for baritone sax) omit the low A extension.
Cheers,
Torsten
