Hi,
in my infrastructure I have a function that binds
(key-signature
#{
\key
#(get-meta-option base-path 'key-tonic)
#(get-meta-option base-path 'key-mode)
#})
but I would like to also change this to Scheme syntax (if it makes any
sense after all).
So? Why don't you do it?
The first call to get-meta-option retrieves a Pitch object, the second
a list ((0 . 0) (1 . 0) (2 . 0) (3 . 0) (4 . 0) (5 . 0) (6 . 0)) which
had been stored as \major.
Obviously \key expects a pitch and a mode, but \displayMusic { \key d
\major } returns
(make-music
'SequentialMusic
'elements
(list (make-music
'KeyChangeEvent
'pitch-alist
(list (cons 1 0)
(cons 2 0)
(cons 3 1/2)
(cons 4 0)
(cons 5 0)
(cons 6 0)
(cons 0 1/2))
'tonic
(ly:make-pitch -1 1))))
where the steps of the scale obviously have already been "transposed"
to reflect d major.
So?
Is it possible to write the Scheme function issuing the key change
with the pitch and the generic mode as input?
(key-signature
(key
(get-meta-option base-path 'key-tonic)
(get-meta-option base-path 'key-mode)))
Obviously I am missing something here.
