It is incredibly important for a vocalist to fully prepare for a vocal session.
It is a huge waste of time for a singer to spend hours trying to perfect a part that he or she has learned that day. The best thing to do is rehearse the part with a rough mix of the of the song at home to be fully prepared, and if the day of the session comes, and the vocalist finds him or herself struggling with a certain part, the best thing to do is to lay down the idea and move on. That way the singer can take the rough home to rehearse.
Time management is very important when it comes to recording so it is essential to know when to move on to stay productive.
