When you first take your seat, you will notice that several of the musicians may already be on stage. Don’t worry; you’re not late. The musicians are warming up and reviewing their music before the concert begins. Just prior to the start of the concert, when all of the members of the choir and/or orchestra are seated, the lights will dim, and the concertmaster will stand and signal to the first oboe player to play the note A. The rest of the orchestra will then tune their instruments to match the oboe. If there is a piano on stage, it may be used to give the pitch from which the orchestra will tune. Then the conductor will enter the stage. He or she will bow to the applauding audience, turn around and begin the concert.
