I want to know the answer to the following question:
What is the name for the practice of singing strictly by the score in opera?
All the background I'm provided with is that "The primacy of the composer's written score has also led, today, to a relatively minor role played by improvisation in classical music, in sharp contrast to the practice of musicians who lived during the baroque, classical and romantic era.". Is that enough to answer the question?
Answer: no
