First interview: broader overview of subject. Second interview: pre-study musical pieces; detailed view of subject with specific examples.
The 'very short introduction to' series, Grout and Taruskin
Don't worry about your interview. Keep calm until results.
Remember this advice isn't official. There is no guarantee it will reflect your experience because university applications can change between years. Check the official Cambridge and Oxford websites for more accurate information on this year's application format and the required tests.
Also, someone else's experience may not reflect your own. Most interviews are more like conversations than tests and like, any conversation, they are quite interactive.
I had two interviews - one was a general conversation with a tutor from another college, who coincidentally was a music
The first interview was a much more broad overview of music and what I thought it was all about. A few topics were extracted from my statement, but nothing major. The second interview had a lot more in-depth analysis, and we were given 10 different pieces to study an hour before the interview. We had to choose 3 and talk about them in detail. I was also asked if I wanted to perform anything on a chosen instrument, or harmonise a chorale.
There aren't that many introductory books for music, but all that there are are extremely useful - the 'very short introduction to' series, Grout and Taruskin all helped massively! My school also did
Don't let anyone or anything get your spirits down about how you did. I know that's really easy to say, but as soon as you have done the interviews, if you completely forget about them, the period of waiting won't be as bad, and the outcome will be a lot more gentle if it goes one way, and a lot more of a serendipitous occasion on the other!
