OK, so you want to transpose this piece. You scan the music, but what  
do you want to do next?

You'll still have to type the notes into Lilypond by hand. There is  
no software anywhere that does a decent job of reading scanned  
scores. (I don't even think there's software that does a bad job!)  
The available technology is too primitive.

But once you type the names of the original notes into your Lilypond  
file, transposing is a simple matter of putting a "transpose"  
statement at the top. You could transpose, print, then transpose into  
another key and print again, with no work at all. But there's no way  
around having to input all the notes by hand first.
