Glad to hear this music here, hope you complete it. There are some undervalued pieces there.
For 16:1 you have a good and stable beginning, but I think it should probably go quite a lot faster. After all it says "Allegro con fuoco". But I sympathize, those large arpeggios are not so easy. It is almost a LH etude and you might apply the usual boring technique to practice in small bursts of speed. Pay attention to arm movement, to get speed you probably need a fluid motion, which is contrary to the reflex when playing it slow when you try to jump the hand to position it for parts of chords.
For 16:2 on the other hand I think you could take it slower and use much more rubato and tempo changes to bring out the poetry. It says "Andante" and "dolce cantando", you play it more like a march. It might help to go a bit softer on the LH. You seem to have this piece very well in hand technically, so you can be free to experiment with expression! Exaggerate wildly (when no one hears!) to find ideas you like.
And yes, another Swede
. Anyone who played the piano seriously in Sweden must have played 16:2 right?
16:1. You are right about the tempo and it was much more difficult than I first understood. There is no way I can read the score at the same time as playing if I go faster so I probably need to learn it completely by heart and after than, practise another month to get it to concert standard. Still, I am not sure I can pull it off at the speed intended without spoiling it.
I think I have found a good fingering for left hand but I probably need to get it into muscle memory to really get it fluid as "arpeggiated chords" and as you say, the arm movement it important to not need to jump to the right positions. More practise!
16:2. You are right again. Listening back to it, you are right saying that it sounds like a march. I think I may have spoiled it for myself as I have more or less known this piece by heart in more than 25 years...and I probably played it better when I was 13 than now :s.
Thanks for your comments and I will try to complete it. I have only played 16:2 before so everything else is knew and I have no recording of them so I do not know how they may sound. From browsing through the rest of the scores, it seems like 16:1 might be the toughest but I am not sure.
