I have a question on what might be possible in a user defined function
with "music" passed to such a function, especially with respect to
how notes are arranged in the etc in the output
Suppose I have a little function like this
MyPattern = #(define-music-function (parser location x y) (ly:music? ly:music?)
#{
$x[ $y~ $y]
#})
And subsequently in my code I call
\MyPattern c8 c16
It seems this wont work as the tie and beaming brackets cause errors.
Perhaps they are not allowed in a function.
Is there any basic way to make this work ?
Perhaps I have misunderstood the ly:music variable
My understanding is that the music variable has pitch and duration information.
Perhaps Lilypond sees the []~ as inferring/corrupting this information ?
