I spent a lot to photocopy the score and make a cut-and-paste solo part. Having done that, it is suddenly falling into place, and is much closer to being comfortable. I guess I have left that plateau. I wouldn’t necessarily say he overcomplicates his music, but he definitely writes thicker chords than are necessary and has this unfortunate tendency to go to sharp keys at the climaxes, which require so much more pressure on the string. I guess the higher tension of the strings equals higher energy for him, though the sound is tighter, so it has a logic to it. I am also certain that the more of his music that you play, the easier it becomes.
Some of it will never be comfortable because of his chord spacings: third, fifth, second for example. Some of the rhythms and tempi are unclear. It is not an easy style of music to play very well. It seems light, but that is only the surface.
