Oh,that syntax is soo hairy.
If you replace

#(define (smart-transpose music pitch)

with

#(define ((smart-transpose pitch) music)

then you can do

\apply #(smart-transpose (make-pitch 0 5 1))

which is much simpler.

I agree.

(define simplify (smart-transpose (make-pitch 0 0 0)))

Eh, haven't tested it. Perhaps I send a patch when I find time to test it.

Again, I agree. I would never use "smart-transpose".
