The two students discuss the upcoming rehearsal. They've heard that the cellist is famous for being an excellent player of the cello, and that he's going to be playing a piece by Mozart in his new orchestra. The students decide to play Mozart's "Allegro Aperto" , which is a concerto for oboe, orchestra, and piano. The oboe is supposed to play solo parts in the piece, but the students decide that they'd rather have the oboe play the entire piece, rather than just one part. They also decide that the oboe should play the cadenza , a brilliant flourish at the end of the piece that is technically brilliant just before the concerto's end. They decide to practice on this piece, and they're interrupted by the arrival of the teacher, who wants to know why the students haven't been practicing yet. The teacher tells them that sensei is in Mexico with her family, and she's been skipping lessons for the past few days. He wants to ask her what's up, and the two students agree to meet again at the next rehearsal.
