Viewing the New Year's Concert keeps me in a good mood for at least a couple of days. Of course, it is somewhat personal with me as I studied in Vienna and attended both concerts and balls at the Musikverein.
The history connected with this venerable institution is great. Beethoven, Schubert, Brahms, Strauss (both the Austrian father/son duo and Richard) Mahler and Liszt are a few whose music was played here. Many also conducted their music here as well. The Vienna Philharmonic was founded by the Musikverein. And on and on.
The gilded music hall was what one associates Vienna with. Baroque, right? Or just lots of wonderful gold and ornamentation.
I would call it "Over-the-top Neo-Classical." Vienna had a huge surge of building after the old wall surrounding the city was torn down. The Musikverein's building is one of the edifices which sprang up during the second half of the 19th century. The Ringstrasse, the road which goes around the center of the city, is where the old wall stood. On both sides of it, one sees the many beautiful buildings constructed after the wall came down.
You are right as regards the instruments. These are workman's pieces, not for show. As to the sound, you could hear it yourself in the dulcet tones of the "Blue Danube."
Austria goes from the high Alps in the West to the flat plains of the Hungarian puszta in the East. The Danube enters Austria from Germany and flows down through Upper Austria, Lower Austria to Vienna and from their onward to Hungary. I guess the area outside Vienna is the least attractive part of the river in Austria. But even that area has its charms.
I think Annie would have enjoyed the concert.
