This sentence stacks two listing patterns — や ('and, among others') for the open-ended noun list, then といった ('such as / things like') to wrap it up as exemplary rather than exhaustive. Together they say 'composers including Beethoven, Bach, and others of that kind.' クラシック as a katakana noun specifically means 'Western classical music' in Japanese — a semantic narrowing from English 'classic.' ベートーヴェン uses the long mark ー and a v-row katakana ヴェ to approximate the German pronunciation; this v-row use is relatively new and still optional.
