Hello, Lukas. I've re-drafted a mock up of the function in question. but
now the mock up actually worked... I was just not adding the hash "#" to
the number argument.... Still, I'll attach the function below to see if it
can be better optimized.
%%CODE BEGINS
%%
someFunction =
#(define-music-function
( ; beginning of arguments
note ; music expression to be repeated and transposed
transposeCoeficient ; number from 1 to 12 that would filter if (or COND)
statements.
) ; end of arguments
( ; beginning of type predicates
ly:music?
number?
) ; end of type predicates
( ; beginning of function block (which is wrong and nonsensical).
make-relative (note) note ; have the transposed note be relative to it's
original.
(cond
((= transposeCoeficient 1 ) #{$note \transpose c des { $note }#} ) ;
statement 1, related to a semitone increase from the original/prime note.
((= transposeCoeficient 2 ) #{$note \transpose c d { $note }#} )
((= transposeCoeficient 3 ) #{$note \transpose c ees { $note }#} )
((= transposeCoeficient 4 ) #{$note \transpose c e { $note }#} )
((= transposeCoeficient 5 ) #{$note \transpose c f { $note }#} )
((= transposeCoeficient 6 ) #{$note \transpose c fis { $note }#} )
((= transposeCoeficient 7 ) #{$note \transpose c g { $note }#} )
((= transposeCoeficient 8 ) #{$note \transpose c aes { $note }#} )
((= transposeCoeficient 9 ) #{$note \transpose c a { $note }#} )
((= transposeCoeficient 10 ) #{$note \transpose c bes { $note }#} )
((= transposeCoeficient 11 ) #{$note \transpose c b { $note }#} )
((= transposeCoeficient 12 ) #{$note \transpose c c' { $note }#} )
) ; end pre cond parenthesis
) ; end of function block
) % end of function
\score {\relative c' {\someFunction c #12 }}

%%CODE ENDS
