The Wiener Musikverein is a concert hall in the Innere Stadt borough of Vienna. It is the home of the Vienna Philharmonic orchestra. The 'Great Hall' (Großer Saal), due to its highly regarded acoustics, is considered one of the finest concert halls in the world, along with Berlin's Konzerthaus, the Concertgebouw in Amsterdam, and Boston's Symphony Hall. With the exception of Boston Symphony Hall, none of these halls were built in the modern era with the application of architectural acoustics, and all share a long, tall, and narrow shoebox shape.
The plans were designed by Danish architect Theophil Hansen in the Neoclassical style of an ancient Greek temple, including a concert hall and a smaller chamber music hall. The building was inaugurated on 6 January 1870. A major donor was Nikolaus Dumba, industrialist and liberal politician of Greek descent, whose name the Austrian government gave to one of the streets surrounding the Musikverein.
The Great Hall's lively acoustics are primarily based on Hansen's intuition, as he could not rely on any studies on architectural acoustics. The room's rectangular shape and proportions, its boxes and sculptures allow early and numerous sound reflections.
Today Musikverein is the most used venue for the annual Vienna New Year's Concert.
References:House of the Blackheads (Melngalvju nams) is a building situated in the old town of Riga. The original building was erected during the first third of the 14th century for the Brotherhood of Blackheads, a guild for unmarried German merchants in Riga. Major works were done in the years 1580 and 1886, adding most of the ornaments.
The structure was bombed to a ruin by the Germans June 28, 1941 and the remains demolished by the Soviets in 1948. The current reconstruction was erected from 1995 to 1999. Today the House of Blackheads serves as a museum and sometimes concert hall.
