In the slower part (such is the extent of my technical vocabulary) at about 2 minutes into the piece, there is an unusual high note followed by a longer pause in the melody than typical for this piece. Then there is a little flourish that brings us back into a more recognizable flow of melody, etc. It is repeated again at 2:45 minutes and then I can't find it again.
It seems odd to me. If you find it, I would be interested in your opinion. To me it does not fit into the melodic phrasing through the rest of the composition and does not seem to justify its existence on its own.
