Hello Dorico crew,
I have found that the Harp template is located inside the Pitched Percussion group. The Harp isn’t a percussion instrument.
Actually it is plucked string instrument, but since Dorico doesn’t have such group, more properly would be if you move it to
the Strings group.
You can check the following books:
Samuel Adler - The Study Of Orchestration
Peter Alexander - Professional Orchestration Vol. 1
Hector Berlioz - A Treatise Upon Modern Instrumentation And Orchestration (Revisited by Richard Strauss)
Thank you in advance!
