I store two pitches in a pair variable
x = #'(b . cis')
But then I want to retrieve each one as a pitch in a music-function
foo = #(define-music-function (parser location bar) (ly:music?)
(define from (car x))
(define to (cdr x))
#{
\transpose $from $to $bar
#}
but when I use this
\foo a
I get Expecting pitch, found (quote b)
So what am I doing wrong and how can I do it right?

PS! The foo function is just a snippet the real function does a bit more...

English isn't my first language.
So any error or strangeness is due to the translation.
Please correct my English so that I may become better.
