Hi thalberg,
First, I must say you were valiant in playing the piano at all, as an ear infection can be painful and can cause balance issues and the dizziness you mention, so it must have been a real distraction. It's much more difficult to play when you're not feeling your best. Nevertheless, you rose to the occasion.
I've not studied this particular Nocturne, so can only speak in general terms this time. I do believe that you turned in a very creditable performance indeed. You brought a lot of poetry to it. I like your treatment of the cantabile line--it's always songful, as it should be. Very nice dynamic contrasts and nuances in your playing too. There is a huge amount of fioraturas or embellishments here--appogiaturas, ever-present grace notes, short trills within figures, short cadenzas, etc! Only Bach could have jammed as many devices into a piece! But well executed, as with your playing, they add much charm to the music. There are also numerous double note figurations, and you voice the tops of those nicely. You play the instances of portato touch consistently throughout, well differentiating it from the surrounding legato passagework. Overall, I believe yours is very expressive playing.
Good work! I enjoyed listening.
