N. B.
I will no longer separate Sibelius Scorch files into different parts (such as soprano, tenor, etc.).
You can do this yourself!
...but first you must download Sibelius 3.1.3 http://www.sibelius.com/download/
If you want to download a Sibelius file, please click on the scorch file, then simply change the ending (file extension) from .sib to .htm
