I'm in a university chamber music group and our director is ambitious, consistently giving us many pieces that are above our level to play with insufficient time to learn them well before performance.
When it's clear that we are not ready to perform, even if we've been practicing the piece for months, she will label it a "reading" on the concert program and have us perform anyway.
I confronted her about it, saying that I felt that was dishonest to the audience. She said that there is a musical tradition of "readings," and she's not calling them "sight readings" so it doesn't actually imply that we are seeing the piece for the first time.
To what extent is that true? What exactly is "a reading"?
