听力原文：W: David, you play the violin, don't you?
M: I did for about 6 years, but 1 haven't practiced much since I came to college. Why do you ask?
W: I'm organizing a performance on Wednesday night. We have a piano player and several bass players, but have only one violin player.
M: Who is directing the group?
W: Janet Hanson. Maybe you have heard of her. She plays the piano in the city orchestra and also directs three small local music groups.
M: Hm, I have my violin here. But I think I'll need to do a lot of work before my playing would sound any good at all.
W: Miss Hanson will give us individual instruction as well as teach us as a group. There' re only 10 of us now. Try to join us.
M: I'm afraid I'm not a good player.
W: Oh, David. I know you can do well. We're all on the intermediate level. And anyway, you won't get a grade for the course.
M: I'll tell you what. I'll play a little this evening and see how it goes.
W: I'm sure you'll be fine. I'll expect to see you at 7 o'clock tomorrow in Room 14 of the Fine Arts Building. I hope you can come to our regular weekly meeting.
