I’ve linked to Dr. Tom Rudolph’s blog before, but Tom’s most recent post is definitely worth a fresh link. He talks about the benefits of using the re-pitching features in your notation software to save time when creating parts:
If you use notation software to notate scores, consider using the re-input pitch option available in both Finale and Sibelius to save time. In my courses and workshops, I find that one of the most under used features of Sibelius and Finale is the re-pitch or re-input pitch option. This feature appeared on an early version of Sibelius and was then introduced later in Finale. It is a great time saver when notating parts especially when writing for band, jazz, string and choral scores where two or more instruments or voices have the same rhythm but different pitches.
