No.

The best way is to go through Scheme, using Music::transpose (the C++
function) Unfortunately, that function is not exported.  I'm a little
reluctant to add features since 1.8 is still stable , and we had a lot
of problems during 1.6 that were caused by adding features.


The best option at the moment is to duplicate some typing work,
ie. have files with

 \score { \notes \transpose X Y \myMusic }
