In the latter part of 2021, it was clear to me that I had lost in D major. All D major pieces sounded in E flat major from the start. This also applied in the Christmas period to the standard carols Joy to the World and The First Nowell. So I was very surprised this evening when watching the Vienna Philharmonic Orchestra’s New Year’s Day concert when that old warhorse, the Blue Danube waltz, was in its unequivocal D major start and finish. Clearly, some warhorses are more deeply ingrained than others.
