On what ground do you have to compare them?I didn't take IB music, but I remember the world lit essays, you could get down to the nitty gritty when comparing (I had to compare/contrast Madame Bovary, Anna Karenina and A Doll's House...it was a grind..)Anyways, I'm thinking for this you could talk about the 'initial' impact of the piece... A lot of video game music embellishes the current scenario, or state. In pokemon, usually frantic music occurs during a Trainer Battle, or when the mood is stressed or whatever. Maybe you can talk about the effect of the motion of both pieces...I'd also maybe talk about the structure? Since it's a 'Symphony' Movement, a harmonic analysis or just analysis of the form would probably be pretty good, and the IB graders will eat that sh*t up. Then maybe compare the pokemon.You'll probably find that the structure of the classical piece is A LOT more sound, and that a lot of the video game music is more through written, or it loops a lot more. So maybe you can talk about the intent of the composer of both pieces... after listening to both, I'm not sure you'll be able to draw conclusions that show too many similarities in the harmonic structure of both (you might...), but the background of the works, why they fit where they do.. etc.Just give me a bit more info on what the paper is about. If it's just a comparative analysis, you can really go any route, as long as you can find some research and stuff to back up the pokemon one...With Alkan you can talk about the 'dazzling virtuosity', or you can talk about transcribing large scale orchestral works to piano, or imitating large scale works...and you can actually find lots of scholarly stuff about that musical era. You might be able to go the route of the pokemon music transcribed to piano, and how it has a different effect from the 8-bit quality sound from the in game music haha.Anyways, this seems pretty interesting! It's a pretty unique grouping of music you have, I just want a bit more info haha.
