What is a fugue? To speak simply a fugue is like a round, that is one voice starts, another comes in a certain distance later, a third voice, a fourth, and it creates a very lovely sound. A fugue is more complicated as the voices do more than just imitate each other, they play contrapuntally against each other, so that when it's not your turn to play the subject you're doing something else. As was seen in Fuga 1, it can get very complex, turgid, intricate and so on. Fugue 2 is less convulted by far than the first one. I should analyze it, find all the main ideas, the episodes and see what I find. I wasn't feeling so well today and it kind of zapped my energy. But I played. I worked mostly on Fuga 2, but I also continue studying Fuga 1 as it will take a while before it's more or less settled in my hands.
Do people ever write poems as fugues? How could you do that? You would of course have to have a few people perform it, but it might be fun to construct one. It's no doubt been done before.
