I like this technique that Stravinsky and Berio use sometimes where only the instruments that are playing display on the score but the spacing remains for the instruments not playing. Helps elements pop out for complex scores. Is it possible to create a score similar to the example posted below?
That is called a “cutaway score” and the Team is aware of some folks’ desire to be able to create them in Dorico, but as Janus says, this has not yet been implemented.
