Finally finished Korngold's transcription of his song Die Schonste Nacht. There are three different versions of this song that I know of, and I play the one based on the piano vocal score from the operetta this is taken from. Here is a recording of that version by Stephen Hough that I just discovered a few days ago.
The most difficult version is the one played by Korngold himself while he sings along. It's quite inspiring because he obviously loves this melody. Korngold was a terrific pianist and embellishes this his version with lots of extra notes and runs. In fact, the person who transcribed this version for me asked if I thought there might be two pianists playing it.
Yunchan Lim, the sensational winner of a recent Van Cliburn competition, has been playing his own version of this piece (which I assume was based on Korngold's Youtube recording) as an encore. I think he plays it very well, but his transcription is not very accurate especially in the harmonies.
