Thank you somuch for this. Grieg was a favorite growing up, I learned many of the lyric pieces when a piano student and loved them all. How perfect he ended his cycle with a nostalgic waltz hearkening back to the very first one.
It is a mirror of his very first lyric piece "Arietta" which makes it evoke even more of a nostalgic feeling. It gives a sense of "how far we've come."
