I don't feel good with this <accidentals> field in K:. What could it be
used for, playing or printing?
Let's start from your last example. In the header, there is:
K:D_B_e=C^F^c
Then, when reading the (automatically printed) score, I will find a
strange key signature (here with a treble clef) which may look like:
---- # ----------------
b
-----------------------
#
---------- b ----------
-----------------------
-----------------------
-- = --
('=' for natural sign)
May I tell I never saw such a thing in my life, and I hope this will
never happen :)
Then again, in the tune, someone wrote:
C, c'
When I try to transcribe this into sounds (by hand, or with a computer),
who can tell me if "C," is shap or not, and the same about "c'"?
Let's go further. Someone in the ABC-land will soon write:
K:C ^e_f
How do you feel "cdefg"?
Let's be serious: standard key signatures are needed by *all* musicians.
When there are strange notes in a tune, these ones shall be indicated by
explicit accidentals. This is (I think) the result of many centuries, so
why had ABC not to follow these basic rules?
