While Chopin called these "Preludes", I have always thought of them as small Etudes. Each presents a unique learning experience in its pianistic challenges, and a few approach a level of great difficulty. No. 7 in A is so profound in its illusory simplicity, that many pianists have made a lifetime study of unraveling its real complexities in order to play it to perfection. My own favorite in that opus, however, is the very atmospheric No. 13--what a joy to play!
i enjoy playing this piece very much. the middle section needs plenty of drama all building up to these clashes of "thunder". and try to bring out the left hand chords in the quieter moments of this section. you also need to make a real contrast between the sections, making the melody as pretty as possible. This is a fun piece to perform (one of the few i have) and is not too technically difficult. however i dont know any recordings!!
I bought Daniel Barenboim's recording. When I did, I found another set by Martha Argerich and to choose between the two, I heard specifically the No.15. There is a huge difference. Martha runs away in the middle section, while Daniel does it slowly and in a controlled fashion, and that is how I think it should be played (that's how I play it at least). It's like the music wanting to run away and you being responsible for not letting it do that. I find it loses all the drama played as Martha Argerich does. I have another recording at home, I guess by Tamas Vasary, and he plays it also too fast for my liking. But hey, my teacher tells me he would play faster than I do, so I guess that's my personal taste only.Alex
