Overview
The Wagner tuba is a four-valve brass instrument commissioned by and named after Richard Wagner. It combines technical features of both standard tubas and French horns, though despite its name, the Wagner tuba is more similar to the latter, and usually played by horn players. Wagner commissioned the instrument for his four-part opera cycle Der Ring des Nibelungen, where its purpose was to bridge the acoustical and textural gap between the French horn and trombone.
The sound produced by this instrument has been variously described as "smoky", "metallic", "unearthly" and "majestic". Wagner tubas (or Tenortuben and Basstuben) are also referred to as Wagnertuben, Waldhorntuben, Bayreuth-tuben, Ring-tuben, or Horn-tuben by German writers, but it is most common to refer to them in English as Wagner tubas. Wagner's published scores usually refer to these instruments in the plural, Tuben, but sometimes in the singular, Tuba.
History
The Wagner tuba was originally created for Richard Wagner's operatic cycle Der Ring des Nibelungen. Since then, other composers have written for it, most notably Anton Bruckner, in whose Symphony No. 7 a quartet of them is first heard in the slow movement in memory of Wagner, and Richard Strauss, who composed several works that used the Wagner tuba, including his Alpine Symphony.
Wagner was inspired to invent the Wagner tuba after a brief visit to Paris in 1853. He visited the shop of Adolphe Sax, the inventor of the saxophone and saxhorn. They showed him a saxhorn, which is similar to the instrument that Wagner ultimately wanted, and later had constructed by the C. W. Moritz firm in Berlin. Wagner wanted an instrument that had the flexibility of a saxhorn and sound of a lur. There are other instruments considered predecessors to the Wagner tuba: Gottfried Weber's double-slide trombone, as well as the Cornon made by Václav František Červený.
