I’m studying Tchaikovsky’s Symphony No. 6 and have come across two lines which look like they are intended to save paper in just showing the musical lines that are playing?
They are everywhere, the next page too.
What’s the proper name for these? And are they for what I had thought initially? To prevent musical instruments not playing just displaying empty staff lines with rests? If you look at the example above it’s just the Viola and Cello.
