This covers composers of art music who died in the last 100 years or so. If you spot mistakes/have suggestions, please use the forum. There are not mems for many composers yet, sorry. Please add your mems to make learning easier!
12/1/2013: I had to re-level the course, and there are now more, and shorter levels. If this has destroyed your previous learning path, I'm sorry. On the plus side, I have added alternatives as answers, i.e. you can just enter years now!
