Hi danilo,
I'm glad you like my Op. 19. Thanks for the compliment! I don't have a big affinity to Schumann's music, but manage to bring some of his pieces off better than others. If you haven't yet listened to the Op. 4 Intermezzo I posted below, but take a moment to hear it, you see what I mean. Hardly anyone plays those pieces anymore, so I had to develop an interpretation from scratch, and the long line flows quite nicely there I think.
On the my pauses between sections in Schumann, you're right, of course. My personal preferences in those artistic matters still need to comport with the intentions of the composer as well as prevailing performance practices. When I think of Chopin, Liszt, Brahms, Schumann and Mendelssohn, I believe it's fair to say that Schumann, more than the others, tends to create those abupt changes in mood--it's attributable to the Floristan vs. Eusebius muses that ruled his musical psyche. I'm just going to have to get "more with the program" with those transitions. Fortunately, we never stop learning.
You raise an important point on score analysis. I do believe analysis is essential and very helpful to understanding a score, but you are quite correct--too much attention to details can inhibit and/or diminish the longer line. Also, if one is not careful, it can squelch spontaneity and lead to "academic" playing. In his day, Hans von Bulow was often accused of that fault. I most often avoid that outcome just by being aware of the pitfall. But it's always a danger.
I also agree with your point on inner lines. Jorge Bolet believed that they must be clearly etched, but not to the extent of hitting the listener over the head with them. So yes, there definitely has to be a sense of balance. In a few of my recordings, there are some scalar inner lines that are probably a bit more prominent than they ought to be. At the time I was working with an artist-teacher. One thing that all of us tend to do is take a suggestion and then unknowingly exaggerate it! A good teacher on a subsequent hearing will tone that down to still retain the necessary effect, but also to restore reasonable balance as well.
Finally, I don't mind the criticism at all. It's all very valuable. Thanks for taking the time to share your thoughts!
