The beloved Vienna Boys' Choir, known here as the Wiener Sängerknaben, isn't just a set of living dolls out of a Walt Disney film (like the 1962 movie Almost Angels); its pedigree is royal, and its professionalism such that the choir regularly appears with the best orchestras in the world. The troupe was founded by Emperor Maximilian I in 1498, but with the demise of the Hapsburg Empire in 1918, it became its own entity and began giving public performances in the 1920s to keep afloat.
From mid-September to late June, the apple-cheeked lads sing mass at 9:15 Sunday mornings in the Hofburgkapelle. Written requests for seats should be made at least six weeks in advance. Tickets are also sold at ticket agencies and at the box office (open Friday 11–1 and 3–5). Expect to pay a top price of €38 for a seat near the nave, and note that only the 10 side-balcony seats allow a view of the choir. On Sunday at 8:45 am, any unclaimed tickets are sold at the entrance. If you miss hearing the choir at a Sunday mass, you may be able to catch it in a more popular program in the Musikverein.
