What is a Vienna horn?

The F single horn used primarily by the Vienna Philharmonic is known as the Vienna horn. The instrument has many characteristics that distinguish it from the standard modern horn, including its use of double piston Vienna valves (or pumpenvalves), an 11mm bore size which is considerably smaller than modern horns, and a double wound, removable leadpipe called a crook (or bogen).

Yamaha is one of very few manufactures currently making Vienna horns. Parts made using exquisite Japanese techniques are sent to Europe, where craftsmen perform final assembly of the instruments and exchange opinions with musicians in Vienna while studying traditional techniques for crafting wind instruments. The product of much diligent work, Yamaha Vienna horns are frequently used at the beginning of the year in the Vienna Philharmonic New Year Concert.
