I thought about writing kazoo, but a little ounce of intuition told me that 12-century music would probably not be arranged with a kazoo part XD
I thought the string instrument was a lute but who knows??? I thought that was the hardest question on the test.
For the last one, once I realised I had to write and not just listen to the awesome song, I talked about pitch as well. I thought there was a lot talk to about in terms of the modulation from minor to major in the chorus and the wide range across the instrumentation.
yeah im of same mind. question one was dumb, and i considered lute and kazoo- came to same conclusion regarding kazoo- and then decided on a "nasal stringed instrument!" wtf.
and omg yes! i was jiving away to myself going NO! you must write now! hahahah. same with the mika one. singing to myself =D
