I've been interested in Messiaen recently, and I decided to learn "Par lui tout a été fait" from the 20 regards. However, it's freaking hard! Just wonderin, has anyone else got a method for learning modern pieces like this?
I could see some re-writing techniques being useful, for instance graphic notation... I mean the first section especially is super formally tight, so I could represent the subject with a certain squiggle and countersubject with another for instance, so it might be possible to condense that bunch of pages into one or two squiggle-maps.
